Description by Ronald LedermannWritten by the developer, not by AppBrain. Click to read.
The best way to explain what the app does is to think that you need to know how much is the 23 % of 1500 pounds, you just put 100(x1) is a 1500 like 23 is a, then the app calculate this automatically, see picture one. Other good example imagen that you have a construction and you know that 20 worker finishing a building in 10 days, but you need it to finished in 5, so how many workers do you need ??. Just put 10 in variable x1 , 20 in z1 and 5 in x2, see picture 2
