What is 15000 × 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.

Multiplication is the process of adding a number to itself a certain number of times. When we say 15000 × 2, we're asking "what is the result if we add 15000 to itself 2 times?"
