Basic algebra rules:


Commutative Property of Addition.

a + b = b + a

Example:

5+6=6+5

Commutative Property of Multiplication.

a * b = b * a

Example:

7*3 = 3*7

Associative Property of Addition.

(a + b) + c = a + (b + c)

Example:

(5+8) + 2=5 + (8+2)

Associative Property of Multiplication.

(a * b) * c = a * (b * c)

Example:

(5*9) * 4=5 * (9*4)



Distributive Properties of Addition over Multiplication.

a * (b + c) = a * b + a * c

(a + b) * c = a * c + b * c

Example:

4 * (5+7) =4*5 + 4*7

(2+7) * 9=2 * 9+7 * 9

The reciprocal of a non-zero real number a is `1/a`.

a*(`1/a`) = 1

Example:

reciprocal of 7 is `1/7` and 7*(`1/7`) = 1

The additive inverse of a is -a.

a + (-a) = 0

Example:

additive inverse of -7 is -(-7) = 7 and - 7+(7) = 0

The additive identity is 0.

a + 0 = 0 + a = a

The multiplicative identity is 1.

a * 1 = 1 * a = a

Basic algebra expressions:

An expression in algebra 1 is a grouping of numbers, variables, constants, operators and parentheses or grouping brackets that are stated as an entity. An equation has an expression on each area of the equals sign. Some expressions are prepared of sub-expressions. Much of algebra concern simplifies expressions to facilitate the solution of equations.

Steps for simplify basic algebra expressions:

Step 1: assembly the terms containing the same variable collectively in algebra 1 expressions.

Step 2: execute the operation inside the parentheses for the variable and other.

Step 3: revise the expressions and simplifying the algebra expressions.

Step 4: To verify the equation, if there is capable to simplify the expression, then recur the step 1 to 4.

Introduction for basic algebra equation:

An algebra equation is mathematical statements that assert the equality of two expressions. Basic algebra equations consist of the expressions that are to be equal on opposite sides of an equal sign, as in

x+3=5

One use of basic algebra equation is in mathematical identities, assertions that are true independent of the values of any variables contained within them.

Laws of addition in basic algebra:

For the addition of positive and negative number, the follow rules, established in the First Course, apply make easy to solve algebra equation:

A number represented by a letter is called a literal number, and any number expression in which more than numbers of symbols are variable is called a literal expression.

Laws for addition in basic algebra:

1)  To add two numbers with similar signs, find the sum of their total values, and prefix the sign common to both.

2)  To add two numbers with different signs, find the diversity of their total values, and prefix the sign of the one with the larger total value.

Basic Probability Calculations

Introduction to basic probability calculations:
The basic probability calculations are very helpful to the students. Calculations are the best tool to study what you want without disturbing the time. Calculation can be more interesting and interact than books and lecturing. Probability is result of examine Probability is number of possible actions divide by total quantity of proceedings. If the event arises it represents like one, or else not occurs it must symbolize zero. Now we will see basic probability calculations.


Example problems for basic probability calculations:


Example 1:- Using basic probability calculations

In school there are 100 students available. In those students, there are 50 students are science group, 25 students are maths group and 25 students are the English group. Find the probability if,

i) Science group students are leaving first from the school.

ii) English group students are leaving second from the school.

Solution:

Given,

Total students n(S)=100

Science group students n(A)=50

Maths group students n(B)=25

English group students n(C)=25

i) Let P(A) is the event of the science group students are leaving first.

So the P(A)=`(n(A))/(n(S))`

=`50/100`

=1/2

ii)Let P(B) is the event of the English group students are leaving first.

P(B)=`(n(B))/(n(S))`

=`25/100`

=1/4.

Example 2:- Using basic probability calculations

The bag has the 60 kerchiefs. In those kerchiefs, there are 15 is the blue color, 20 is the yellow color and 25 is the white color. If John select the white color kerchief means solve the probability?

Solution:

First list the given information,

Total kerchiefs n(S)=60

Blue colour kerchiefs n(A)= 15

Yellow colour kerchiefs n(B)= 20

White colour kerchiefs n(C) = 25

Assume P(E) is the probability for john select the white colour kerchief.

So P(E)=`(n(C ))/(n(S))`

=`25/60`

=`5/12` .

In the above way we can solve the problems.

Having problem with Uniform Probability Distribution keep reading my upcoming posts, i will try to help you.

Example 3:- Using basic probability calculations


Two coins are spinning. What is the probability for if two head are receiving?

Answer

Two coins flipped means the feasible outcomes are {(H,T),(H,H),(T,H),(T,T)}

So the total numbers of outcomes are 4.

We get the two head possibility is 1.

Probability = 1/4.

Example 4:- Using basic probability calculations

Solution:

Probability for finding above 25 scores:

Above 25 scores=41, 46, 27, 79.

In the given scores the above 35scores probability values are (41, 46, 27, 79)

Probability for above 25 scores=41+46+27+79

=193.

Total scores values = (41+13+46+27+79+25+15) =246.

Probability=above 25/Total given scores.

Total scores=246

Probability for above 25 scores=`193/246` .

=`193/246` .

Formulas for finding probabilities for below 25 scores are,

Basic Geometry Concepts

Introduction to basic geometry concepts:

In basic geometry concepts, the geometry is all on the subject of shapes. Geometry was enormously major to prehistoric societies and was used for surveying, astronomy, direction-finding, and structure. Geometry is the study of angles and triangles, outer limits, area and quantity. It differs from algebra in that one develops a reasonable formation where mathematical relations are prove and functional.

Basic Geometry Terms:

Some of the basic terms in geometry are line, rays, angles, and plane.
Now we will discuss about basic concepts in geometry.
Line segment:

In these basic geometry concepts, a line segment is a straight line up segment which is division of the straight line among two points.
To organize a line section, one can inscribe AB.
The points on each surface of the line division are referred to as the finish points.
Ray:

In basic geometry concepts, a ray is the element of the line which consists of the arranged point and locates of all points on one elevation of the closing stages point.
Angle:

In basic geometry concepts, angle can be discrete as two rays or two line segments having a common finale position.
The endpoint becomes predictable as the vertex.
Angles come about while two rays accumulate or mix up at the matching endpoint.

Plane:

A plane is often instead of by a blackboard, communication board, a plane of a box or the peak of a table.
These 'plane' surfaces are damaged to connect any two or added points in a straight line.
A plane is a parallel frontage.

Types of Angles:

An angle is different as wherever two emission or two-line segment join mutually at a general endpoint is known as vertex.
In basic geometry concepts having some types of angles. these are,
Acute angle.
Right angle.
Obtuse angle.
Acute angle:

I like to share this Acute Angled Triangle with you all through my article.

An acute angle procedure a lesser of that 90°
Right Angle:

A right angle connections correctly 90°
Obtuse Angle:

An obtuse angle measures not required than 90° but less than 180°

Math Factors of 59

Introduction to math factors of 59:

Math factors are the numbers that we do product in show to get another number:

For example the number 6 has the factors 1, 2 and 3 as shown as follows,

6 =1 x 2 x 3

In this article we are going to learn how to factorize the numbers and all about the math factors of 59.


Math factors of 59:


In order to get the factors we have to divide with the numbers starting with the number 1.

Let us do the math factors of 59.

Step 1: Divide the number 59 by 1 we get 59.

Step 2: We can’t divide 59 further as it is a prime and it gives the result with the decimal

Point.

Step 3: Finally the factors of 59 are 1 and 59.

That is 59 = 1 x 59.

That is 59 = 59 x 1.

Note: prime number is a number which is divided by 1 and the number itself.


Example problems- Math factors of 59:


The following examples will make you clear about how to factorize the numbers in math.

Example 1:

Find the factors of 159

Solution:

Step 1: Divide the number 159 by 1 we get 159.

Step 2: As it is a odd number we cant divide it by 2 therefore it is better to go with 3

Step 3: Divide 159 by 3 :

159/3 = `(3*53)/3`

= 53 (where 3 cancels each other)

Step 4: As 53 includes in the above step it is also a factor of 159.

Finally the factors of 159 are 1, 3, 53 and 159.

That is 159 = 1 x 159;

That is 159 = 3 x 53;

That is 159 = 53 x3;

That is 159 = 159 x 1.

Example 2:

Find the factors of 259

Solution:

Step 1: Divide the number 259 by 1 we get 259.

Step 2: As it is a odd number we cant divide it by 2 therefore it is better to go with 3

Step 3: Dividing by 3 is also not possible so Divide 159 by 7 :

259/7 = `(7*37)/7`

= 37 (where 7 cancels each other)

Step 4: As 37 includes in the above step it is also a factor of 259.

Finally the factors of 259 are 1, 7, 37 and 259.

That is 259 = 1 x 259;

That is 259 = 7 x 37;

That is 259 = 37 x 7;

That is 259 = 259 x 1.

Example 3:

Find the factors of 359

Solution:

Step 1: Divide the number 359 by 1 we get 359.

Step 2: We can’t divide 359 further as it is a prime and it gives the result with the decimal

Point.

Step 3: Finally the factors of 359 are 1 and 359.

That is 359 = 1 x 359.

That is 359 = 359 x 1.

Basic Notes on Algebra

Introduction to basic notes on algebra:

Algebra is defined as the major part of mathematics which deals with the study of laws of the operations and those concepts which involves various polynomials, algebraic structures and the equations. There are various kinds of algebra which includes elementary algebra, abstract algebra, etc.

In this article we are going to see about the basic notes of algebra which includes various laws and some example problems.

Basic notes on the laws of algebra:

laws of algebra:

There are various laws that are used in algebra for solving the equations and various algebraic structures.

The first basic notes on algebra are addition which involves the commutative law.

It states that a + b = b + a

Example:  5+6 = 6 + 5

11 = 11

The commutative law can also be applied for multiplication.

The basic law for multiplication is given by

a * b = b *a

Example:    5* 6 = 6* 5

30 = 30

We can also use the associative law for both the addition and the multiplication.

The basic notes for the associative law in algebra for addition is given by

(a + b) + c = a+ (b + c)

Example: (1+2) + 3 = 1 + (2+3)

3 + 3 = 1 + 5

6 = 6

The associative law for multiplication is given by

(a * b) * c = a*(b * c)


Example: (1*2) * 3 = 1* (2*3)

2 * 3 = 1 * 6

6 = 6

The next important basic notes of algebra include the distributive law.

(a * b) + c = (a*b) + (a * c)

Example: (1 * 2) + 3 = (1 *2) + (1 * 3)

2 + 3 = 2 + 3

5 = 5

Understanding Quadratic Formula Problems is always challenging for me but thanks to all math help websites to help me out.

Notes on basic rules of algebra:

The additive inverse of a is given by –a for any constant or a variable.

Example :a + (-a) = 0 and 5 + (-5) = 0

The multiplicative inverse of a is 1/a for any constant or a variable.

Example: a * 1/a = 1 and 5 * 1/5 = 1

In case of addition the identity element is zero for any constant or variable.

Example: a + 0 = a and 5 + 0 = 5

In case of multiplication the identity element is one for any constant or variable.

Example: a * 1 = 1 and 5 * 1 = 5.
