When you square a number, you multiply it by itself. In mathematical notation, this is written as x2.
For example:
52=5×5=25
2.52=2.5×2.5=6.25
(−3)2=(−3)×(−3)=9
Remember that when squaring a negative number, the result is always positive because negative × negative = positive.
This calculator can handle both integer and decimal numbers, and will display the result in standard notation for manageable numbers or scientific notation (1.234e+10) for very large or small results.
