Numeric expressions apply operations to numbers. For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.
Oh man, this is the easiest college level math question that I could find as a middle schooler. I would say 8, but it's probably the wrong answer, so um bye.
