How to Do "Squared" on a Scientific Calculator

Scientific calculators have a squared button.

Squaring a number refers to multiplying a number by itself. For example, five squared would be the same thing as saying five times five. The "squared" function comes in handy when figuring the area of a square because the length and the width are equal. Using a scientific calculator makes it very easy to compute a squared function because they have a squared button.

Instructions

1. Clear your calculator by pressing the on button, sometimes labeled "AC."

2. Enter the number you want to square. For example, if you want to square seven, you would enter "7."

3. Press the squared button on your calculator, usually denoted as "x^2," and your calculator will show the answer. In this example, after you pressed the squared button you would see "49."
