Estimate!

Estimation is the art of thinking up strategies to find an answer to a simple arithmetical problem in a short time. You don't have to do an exact calculation and come up with the exact answer, but an answer that is fairly close to it will do. In Estimate! an answer is okay if it is at most 5-10% off the real exact answer. The way people come up with estimation strategies is quite personal and in many cases everybody has another strategy. The simulation you can play here does not have the intention to provide you with those strategies, but tries to motivate you to come up with strategies yourself.
