Question

How can you determine is a math question is an equation or an expression?

Answer 1

An equation will have an answer at the end like an equal sign. (Ex; 20+20=40)

An expression will NOT have an answer. (Ex; 20+20)

Answer 2

The difference between an equation and expression in maths is that an expression is a combination of numbers, variables and symbols to be calculated. An equation contains expressions that are separated by an equals sign.
