You're percentophobic, you don't like percentages (or Cross-Multiplication don't like you, I'm not here to judge)? This is great, computers love to calculate the VAT or sales for you!

You need to calculate the original price, the percentage discount or the reduced price ? No problem, fill informations you know, and the application will do the rest!
It automatically detects what you want to calculate. And if this is not the case, you can change the element to calculate by clicking the small button on the left of the text box.

You can also calculate the Cross-Multiplication (rule of three).
