Nothing slows down a DIY faster than some complex math, and nothing can speed it along like these tools, tech, and tips that make common calculations a breeze.

Find \(\frac{1}{5}\) of \(20\), then multiply by \(3\). Find \(\frac{1}{5}\) of \(20\) by dividing \(20\) by \(5\). \(20 \div 5 = 4\). We need \(\frac{3}{5}\) of \(20 ...

If you were to add \(\frac{1}{2}\) and \(\frac{1}{3}\), it is hard to picture what the answer would be. Rewriting the fractions with a common bottom number, or denominator (in this case, \({6}\)), ...
