Basics of algebra

Evaluate for a=2 and b=6 a²+2b

The operator of an algebraic expression are the symbols + - * and /

In an algebraic expression, the like terms are the ones with same variable and different exponent

Evaluate the expression: 12x - 3 = 9

Select the variable of the term 4ab

the constant of the algebraic expression is 3x-9x=12

Simplify 12x³+3y-x³+2y

In an algebraic expression, the terms are separated by a:

Is x+4= 8 if x=3?

How many terms are in this expression: 6a+5ab-2b
