Basic Algebra For


Introduction of Basic Algebra For:
Algebra is the branch of mathematics concerning the study of the rules of operations and relations, and the constructions and concepts arising from them, including terms, polynomials, equations and algebraic structures. Together with geometry, analysis, topology, combinatorics, and number theory, algebra is one of the main branches of pure mathematics. The part of algebra called elementary algebra.

Basic Algebra for Addition and Subtraction:

The followings are some of the examples for basic algebra of addition and subtraction.

Addition of fractions:  `4/9 ` +` 4/9` .

Solution:

From the fraction denominators are same.

By adding the numerator and same as in the denominator:

= `4/9` +` 4/9`

=` (4 +4)/9`

=` 8/9`

By Simplify and adding the fraction:

= `8/9`

= `4/3`

Subtraction of fractions: ` 2/6` - `4/6` .

Solution:

From the fraction denominators are same.

By subtract the numerator and same as in the denominator:

= `2/6 ` - `4/6`

= `(2- 4)/ 6`

=` -2/6`

By Simplify and subtract the fraction:

=` -2/6`

= `-1/3`

Algebraic expression of addition: 10x + 7y + 3x + 5a.

Solution:

The given expressions are 10x + 7y + 3x + 5a

The like terms in expression are 10x and -3x. We cannot do anything the 7y or 5a.

Then group the terms and add.

= (10x + 3x) + 5a + 7y

= 5a + 13x + 7y

I have recently faced lot of problem while learning Compound Interest Equation, But thank to online resources of math which helped me to learn myself easily on net.

Basic Algebra for Multiplication and Division:

The followings are some of the examples for basic algebra of multiplication and division.

Multiply the integers: 5 × 9.

Solution:

Given integers are (5) × (9)

= |5| × |9|

= 5 × 9

= 45 is the solution for the given integers.

Multiply the integers: 4 × (-5).

Solution:

Given integers are 4 × (-5)

= 4 × -5

= 4 × -5

= -20 is the solution for the given integers.

Divide: 8a^2 – 40 by 8

Solution:

The given polynomials are 8a^2 – 40 ÷ 8

= `(8a^2-40)/8`

By dividing them we get

= `(8a^2)/ 8` * `-40/8`

= a^2 - 5

Divide: 12a^2 – 24 by 4

Solution:

The given polynomials are 12a^2 – 24 ÷ 4

= `(12a^2-24)/4`

By dividing them we get

= `(12a^2)/4` *` -24/4`

= 3a^2 - 6

Equivalent Definition Math


Introduction to equivalent definition math:

The equivalent is the term in the mathematics. It defines the equivalent definition fractions math and the equivalent ratio for the numbers. The fraction of the two numbers has the equivalent fraction for the fraction of other two numbers. Here we are going to see about the equivalent fraction for the two numbers.The equivalent fraction may be find by the common multiplication or the division of the common number in both numerator and also the denominator. I like to share this Derivatives Table with you all through my article.


Example problems for equivalent definition math:


Example 1 for equivalent definition math:

Find the equivalent fraction for `2/5` .

Solution:

The given fraction is `2/5` .

We have to find the equivalent triangle, for that we multiply or divide the numerator or the denominator by the common number to get the equivalent fraction.

Multiply the above fraction by 5 on the denominator and also numerator

`2/5`  `xx` `5/5` = `10/ 25`

Multiply the given fraction by 3 also we get the equivalent fractions.

`2/5`  `xx` `3/3` =` 6/ 15`

Divide the given fraction by 4 to get the equivalent fractions.

`2/4``-:` `5/4`= (`2/4` )/ (`5/4` )

`2/4``-:` `5/4`   = `2/5`  `xx` `4/4`

`2/4``-:` `5/4`   = `8/20`

Divide the given fraction by 8 to get the equivalent fraction.

`2/8``-:` `5/8`  = (`2/8` ) / (`5/8` )

`2/8``-:` `5/8` =` 16/40`

The equivalent fractions of `2/5 ` are `10/ 25` ,` 6/ 15` , `8/20` and `16/40` .


Example 2 for equivalent definition math:

Find the equivalent fraction for `4/7` .

Solution:

The given fraction is `4/7` .

We have to find the equivalent triangle, for that we multiply or divide the numerator or the denominator by the common number to get the equivalent fraction.

Multiply the above fraction by 2 on the denominator and also numerator.

`4/7` `xx`` 2/2` =` 8/ 14`

Multiply the given fraction by 5 also we get the equivalent fractions.

`4/7` `xx`` 5/5` = `20/ 35`

Divide the given fraction by 3 to get the equivalent fractions.

`4/3``-:` `7/3` = (`4/3` )/ (`7/3` )

`4/3``-:` `7/3` = `4/7`  `xx` `3/3`

`4/3``-:` `7/3` = `12/21`

Divide the given fraction by 9 to get the equivalent fraction.

`4/9``-:` `7/9`  = (`4/9` ) / (`7/9` )

`4/9``-:` `7/9` = `36/63`

The equivalent fractions of `4/7 ` are `8/ 14` , `20/ 35` , `12/21` and `36/63` .

Having problem with math algebra 2 help keep reading my upcoming posts, i will try to help you.

Practice problem for equivalent definition math:


Find the equivalent fraction for `1/7` .
Answer: `2/14` , `4/28` , `5/ 35` .
