What is 25 × 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 one of the four basic operations in arithmetic, along with addition, subtraction, and division. When you multiply two numbers, you're essentially adding the first number to itself as many times as the second number.

In the case of 25×2, you're adding 25 to itself 2 times.
