At the end of the levels you will receive a grade, and when you answer the questions it will tell you if you are correct or wrong. Most questions in Version 1 of Math fun are not cheat proof which means that if the question is 14*14 then you could put 14*14 as the answer and get it correct. Later versions will eliminate this. |

| **mathhandler.zip** | 2k | 03-03-30 | | **Math Output Handler** Math Handler is a simple program (only 101 bytes) that I wrote at school one day. It takes your input of an expression in the same way that the normal calculator OS does and displays it as a decimal AND a fraction at the same time. It has other features than that, as it is easy to control (simply enter + to exit), doesn't display the fraction if the answer is a whole number, and enables the use of [Ans] when it was previously not enabled. Trust me, it may sound stupid, but it really saves time in simple arithmetic. See the screenshots for examples. Math Handler will save you time! |

| **wannabhp.zip** | 1k | 07-10-26 | | **I Wanna Be an HP** This is just a run-of-the-mill RPN calculator. RPN means "Reverse Polish Notation" and is the default notation used on HP calculators, so that's how I came up with the title. The main difference between this RPN program and the others is that it's prettier -- there's a little title screen with an anthropomorphic TI-83 saying "I WANNA BE AN HP!" and the program itself runs in a pretty split-screen mode with 3D-looking buttons. I wrote it for CalcG.org's contest (somebody else won). All you have to do is download it, unzip it, send WANNABHP to your calculator, and run it. The rest is explained on-screen. |
