Think Fast!

The story for this counting game isn't important. It's just about a space shuttle getting into a Black hole and the only person who save it is one technician - you. You won't connect any wires or work hard because you are going to count. The difficulty is about deciding if you want simple mathematics or the difficult one. The easy is really simple but when playing the most difficult you will probably need a calculator. The arithmetical problems fall down and you must right the correct result. The game isn't for everyone and only people, who want to practice the math, will enjoy it.
