→Your Child and the Computer
Today, computers are involved in almost every aspect of life. Working with this cartridge can help your child become familiar with computers and their operation. Since computer-enhanced instruction is more common in the classroom every year, this knowledge can give your child an important advantage.
===Playing Alien Addition===
When the game begins, five alien space ships are displayed at the top of the screen. Each ship has a different addition problem on its side. The space ships make a beeping sound as they advance, one by one, toward the laser cannon at the bottom of the screen.
The object of Alien Addition is to "equalize" the attacking ships before they reach the laser cannon and destroy it. To do this, your child positions the laser cannon beneath an alien ship, displays the answer to that ship's problem on the laser cannon, and fires the cannon. When the answer on the cannon is correct, the laser blast equalizes the alien ship and a hit is scored.
Equalizing an alien ship causes it to explode with a shower of red sparks. Each time a ship is equalized, another ship with a new problem takes its place at the top of the screen, and the attack continues.
====When Your Child Misses a Problem====
If the number displayed on the laser cannon is not the correct answer to a ship's problem, firing the cannon at that ship scores a miss. A ship that is fired upon and missed advances out of turn. Any alien ship that is not equalized before it reaches the cannon range at the bottom of the screen destroys the laser cannon. When this happens, the laser cannon explodes into an ominous, grey cloud. If alien ships destroy three laser cannons before the game's time limit has expired, the game is over.
