An online maths game with an almost infinite supply of math addition problems to solve.
Once you have clicked on your choice, a random question will appear which you have to solve by clicking on the numbers in green, in the white boxes at the bottom of the blackboard. Sums in the second and third level have a green box around the column of numbers that you should solve first. They also have a carry one button below the sum's bottom line, when you have an answer to that column which is greater than ten. You will be told visually and audibly whether you have got the answer correct or not. When you are able to try the next sum, the Next Sum button will become active at the bottom of the board. At any time you can try a new level by clicking on the New Level button at the bottom.
