Let's try it!

You got this and I believe in you!!!! <3 Miss Issa

Squaring a number is raising that number to the power of ^two.

This tells you that you should multiply that number by itself. For example 5² means 5x5, which is just 25.

Taking the square root of a number is the opposite of squaring it.
