Numbers Bee app for iPhone and iPad

Numbers Bee improves Numeracy and Number Sense for children of all ages.
You are given the desired result and four numbers and four operators (+, -, X, /). You must use all four numbers and use any of the operators to get the desired result. The games are timed to help you measure how quick you are in solving them. You learn order of operations and negative numbers in a fun way. Games in the lower levels contain only two operands and two operators.
There are twenty four levels of increasing difficulty. You can choose any level to play from the slider at the bottom of the screen. The earlier levels contain games that can be solved through addition and subtraction. Higher levels contain multiplication and division operators as well.
All games are randomly generated. You literally have more games than you can play in a lifetime at your fingertips.
Most games have more than one solution. A wizard assists you in giving you all the possible solutions for a game.
Have fun!
