What is 240 × 2?

Mathematical expressions are a combination of numbers, variables (like x, y, or z), and operators (like +, −, ×, and ÷) that represent a particular value or quantity. For example, 2+3 is a simple mathematical expression. The + is an operator that tells us to add the two numbers together.

The operation "×" is called multiplication. When we say "240 × 2", we're actually adding 240 to itself once (since multiplication is repeated addition).
