Math is fun

This website is only for those who want to know about math, please post feedbacks to help me post more topics of school topics.

Algebra:

There are 4 types algebra:

Addition

Subtraction

Multiplication

Division

Let's talk about the addition in algebra.

Rules:

Algebra can only be added with like terms

Like terms example: 5a and 4a

Unlike terms: 3x and 2v

Addition in algebra: 6a+5b+7a

Add the algebra with the like terms: 6a+7a = 13a

then: 13a+5b Done!

Answer this: 5a+45b+7s+23a= ?

Let's move on to subtraction, the rule is the same with the addition, but only subtracting

Example: 89a-56b-34a

= 123a-56b

Answer this: 230b - 34n +123b-45n= ?

Multiplication Algebra

Rules:

Unlike addition and subtraction, it can be multiplied with like and unlike terms ( with different values coefficients).

Example: 15c X 3v = 45cv

If it is with the same coefficients, it would have power

Example: 15x X 3x = 45x2

Answer: 14c X 2b - 12b X 5v = ?

Division algebra

The rules is the same with multiplication, only division.

Example 22x : 2v = 11xv

If it is with the same coefficients, coefficients -1

Example: 45x : 15x = 3x

If it has a power, minus the power

Example: 15x2 : 3x= 5x
