Squared Calculator

Use the calculator above to square any real number (positive, negative, or decimal). See below the step-by-step method, the formula, and the squared numbers tables.

Step-by-Step: 265 Squared

Squaring a number means multiplying it by itself. To compute 265²:

1. Write the number twice:
   265 × 265
2. Multiply to get the result:
   265 × 265 = 70,225

265² = 70,225

Formula

The square of a number n is defined as:

n² = n × n

Equivalently, in exponent notation: n² (read as "n squared" or "n to the second power").

Geometrically, n² represents the area of a square with side length n — that's where the name comes from.

Key property: for any real n, (-n)² = +n². The square of any real number is non-negative because two factors of the same sign always multiply to a positive value.

How to Square a Number

1. Write the number you want to square.
2. Multiply it by itself once: n × n = n².
3. If n is negative, parenthesize the number when writing each factor: (-n) × (-n) = +n².
4. For a decimal, multiply just like a whole number — line up and the result has twice as many decimal places.
