DEFINITION:
An algebraic expression is a mathematical phrase that can contain ordinary numbers, variables (like x or y) and operators (like add,subtract,multiply, and divide)

HOW TO:
A + 1

I be working out expressions (expressions)

Hey! Hey! It’s expressions

Aye, I be working out expressions

Hey! Hey! It’s expressions

Aye, I be working out expressions

Expressions are numbers or operators like the plus or the minus

It’s all simple equations

Like 2 times 3 is a mathematical phrase

You can rearrange numbers to solve it multiple ways

An expression can contain numbers, letters and symbols

Let me help you break it down I can make it real simple

Like 2 + X =10

Find the value of x?

This is an expression

So, all you have to do is look on the left side of the equation

it’s addition it’s time to expand your mind

And on the right side you just got to do the opposite

And use subtraction to find the main operate

See the main goal is to get the X all by itself

Subtract the 2 from the 10 and you’ve got 8 left

So, that’s how you solve it

You can handle these expressions and you’ll be making ‘A’s regardless of any lesson (Ha)

Aye! Aye! I be working out expressions

Yea, I be working out expressions

Aye! I be working out expressions

Yea, I be working out expressions
