Years ago, no math education was complete without understanding how to compute a square root. Today, you are probably just ...

After seeing an exhibit of an old relay-based computer as a kid, [Simon] was inspired to build a simple two-relay latching circuit. Since then, he’s been fascinated by how relays can function to do ...

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 ...

Mastering quick square root calculations boosts maths exam performance. Speed and accuracy provide a significant advantage in algebra and geometry. Memorising key square roots and using mental math ...

Square-root-calculating circuits find wide use in instrumentation and measurement systems for such tasks as calculating the rms (root-mean-square) value of an arbitrary waveform, for example. Hence, ...

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 ...
