## The calculation of the square root of the number

To calculate the square root of the numbers in the spreadsheet editor of Microsoft Excel you need to enter the number in the first cell of the table. To do this, use the mouse cursor to highlight the desired cell and type the number in its field. When you are finished typing hit the "Enter" button on the keyboard that will mean the end of the operation and will allow the computer to process the information entered.
