Dreisatz — rule of three

▶ »Dreisatz« enables you to calculate the rule-of-three easy, fast and comfortable. The rule-of-three is a mathematical method to determine an unknown fourth value out of three known values. If 1 apple (a) cost 4 bucks (b), how much are 2 apples (c)? The answer is 8 (x) and this task was supereasy. For more complicated calculations, we made »Dreisatz«. If just everything depending math could be that fun! We’re contantly updating the app to deliver the best possible user experience for you.
