Simple Pyramids is a very simple application which helps kids to practice problems in addition and subtraction.
Each brick's number is the sum of the two numbers under it. Place the missing numbers in the empty bricks. By pressing the 'Check' button the application tells you if the entered numbers are correct. Fields with a correct entry are colored green. Fields with an incorrect entry are colored red. Users can also print a simple worksheet, so kids can practice without sitting in front of an computer.
