【實用教育app】Elementary Math Game|最夯免費app-綠色工廠好玩App

There are five simple operations which a grade school student learns: addition, subtraction, multiplication, and that dreaded division. Wait?!? that's only four!

This project is simple to make and easy to play. It has three different skill levels which allows grade school kids to learn and practice their skills while playing a game, and more difficult levels that will challenge almost anyone. As the clock runs down, pressing you for time, you must try to solve the problems one after another.

The game is child's-play.

You have a current value which you try to manipulate into the target value by using the keyboard and the assigned operation. When you click on a numbered button, that number is the second operand in the mathematical operation. EX: pressing the number '2' will result in 43÷2=21 (values are rounded down to the nearest integer). Since this 21 is not the target value 26, the current value of 43 is replaced by 21 and the clock keeps counting down. The list of 'next operations' is shifted over, and the symbol that was on the left most end of that list is the new 'assigned operation'. This continues until the target value is reached and a new level, or problem, is generated and the clock is reset. It can be a lot of fun, and the Hard level is pretty tough too, so even if you think you're a wiz at math, this is probably better than playing Solitaire at the office. Remember grade four? When 23÷7=3 remainder 2? Well, in this game, you'll discover that elusive 'fifth operation' called 'modulo'. It basically asks 'if I divide one number by another number what is the remainder?', and so 23 modulo 7 is equal to 2.
