3.
Expressions
Statements of value
4.
Terms
A coefficient and a variable together
5.
Coefficients
Numbers directly in front of symbols
6.
Variables
Symbols representing a value
7.
Equal/Equivalent
An expression or term that has the same value as another
You multiply the coefficient by the variable
8.
Constant
A number in an Algebraic expression that is alone
9.
Inverse Operation
The opposite Operation to the one you have (the inverse Operation to addition is subtraction)
10.

12.
3+x=12
This is an equation.
13.
3+x=12
We are trying to find the value of x.
14.
3+x=12
You then use the inverse Operation. (in this case, the inverse option of addition is subtraction)
15.
3-3=0 12-3=9
You then (in this operation is addition) subtract he number of the constant from itself, and the equivalent.
16.
X=9
The number you get after using the inverse Operation on the equivalent is the value of the variable.
