If two things are equivalent, they are the same. Equivalent expressions are expressions that are the same, even though they may look a little different. If you plug in the same variable value into equivalent expressions, they will each give you the same value when you simplify.

Beside this, what is an example of an equivalent expression?

Examples of Equivalent Expressions 3x+2 and 3x + 6 are equivalent expressions, because the value of both the expressions remains same for any value of x. For instance, for x = 4, 3x+2 = 34+2 = 18 and. 3x + 6 = 3 x 4 + 6 = 18.

Likewise, what is a numerical expression? Numerical Expression Definition. A numerical expression is a mathematical sentence involving only numbers and one or more operation symbols. Examples of operation symbols are the ones for addition, subtraction, multiplication, and division.
