Microsoft Excel is a powerful tool for carrying out complex calculations. If you work on Excel, then you might come across performing mathematical operations almost every day. Sometimes, we face ...

Somewhere around middle school, you learned about squaring numbers and the inverse, finding the square root of a number, but a little reminder can't hurt. You square a number when you multiply it by ...

We have seen the use of digital roots to check various calculations. Today we look at how we can make use of digital roots to find square roots. There are two uses of digital root in squares. It helps ...

Roots are the opposite of powers. As 2 squared is 4, then a square root of 4 must be 2. \(2^2 = 4\). Reversing this gives \(\sqrt{4} = 2\). To find square roots or cube roots, work backwards from ...

The square root of a number N is a number which, when squared (multiplied by itself), results in N. How did the ancient Greeks find square roots? Their method is nowadays called a ‘Greek ladder’, ...
