BlitzResults: Maths-Infosite & Interactive Calculation-Tools

How does percentage calculation actually work, again? How many calories are burnt in an hour of jogging? And how much electricity does the washing machine really cost me? Isn’t it amazing how many of our everyday questions and problems can be solved with mathematics?

Unfortunately, our math skills are sometimes a little rusty. Or, we simply don’t have the time to calculate. Sometimes the bill, in itself, is quite simple; but you have to laboriously research certain values (or do you happen to know off by heart how many calories are consumed while jogging?).

We want to change that! On Blitzresults you can find a variety of free online-calculators that will quickly deliver the appropriate solution. Plus a lot of background information on the respective subject and all formulas.
