These two programs are designed to test the youngsters on simple addition and subtraction, but do require adult supervision.

Sums For Fun has two difficulty levels, for whether your child is able to count up to 10 or 20, and progresses through three stages.

The child's name is entered, then he or she is asked if they would like to count in apples, lemons, cherries or oranges.

Five questions follow, illustrated by the graphic chosen. After each answer has been input the screen clears and a right, wrong or well done message appears in large letters.

At the end of the round a score is given. Should this be satisfactory, further questions are provided in Stage 2. These are asked as sentences without the use of graphics.

A sufficient score after five of these questions begins Stage 3 where sums are given in the conventional A+B=? format.

Taking Away For Fun is similar, but questions are asked in only two stages.

The first offers graphics displays of ships, cars, fish or birds. The second uses conventional A-B=? subtraction, but does give a graphics illustration of how the correct answer is obtained, should the wrong one be entered.
