This is a computation drilling program, which means that although it is likely to be sold under an 'Educational' banner it doesn't teach you anything. All a program like this can do is give you practice at something you already know; it is the equivalent of a book of sums.
The one thing that such programs offer is the motivational element which the colour, graphics and sound of the computer can give. The 'interest' in this case is a helicopter with which you select the right answer, and which lifts the answer into the sum. If you are wrong it crashes to the ground.
On the negative side: there are no difficulty levels in this program, you either work with answers up to 99 or you don't. The program gives you the right answer after two wrong attempts, but it will carry on with the sum for ever if you refuse to copy the one given.
Above all it's boring after one session. One to avoid I feel.
