What Is a Square?
In mathematics, the square of a number is the result of multiplying that number by itself.
Formula:
Square = Number × Number
Examples:
- Square of 4 = 4 × 4 = 16
- Square of 10 = 10 × 10 = 100
- Square of 0.5 = 0.5 × 0.5 = 0.25
- Square of -7 = -7 × -7 = 49
A square calculator automates this process for you instantly.
