Side 1 - Fractions from decimals
Side 2 - Percentages

Each program is in two parts. The initial stage allows the teacher or parent to select the time allowed for each question and its level of difficulty. Once these conditions have been set then the child takes over. CTRL-L can be used at any input (where the cursor key flashes) to reset the levels. The child is then confronted one at a time, with ten problems.

Top left of the screen shows the number of problems correct and top right the number of problems remaining. If the answer is wrong then the child is allowed to try again, if wrong a second time then the right answer is given. If the child gets more than six out of ten then he is allowed to play a space game.

Spacecraft are sighted, they must be destroyed as quickly as possible. Move the gun sights using the cursor keys and fire using the space bar, but beware of your shileds being destroyed and running out of laser energy. Score displayed top left, high score - top right. If all aliens are destroyed and number of problems answered is greater than ten and the offer of another go is declined then the core is entered into the Hall of Fame - decisions, decisions!

N. B. If more than six out of ten is obtained on three consecutive turns then the level of difficulty automatically increases by one. Except level 4 which should be used primarily for calculator practice.

Where necessary, answers must be given to three decimal places. The DELETE key is used to erase figures entered in error.
