Most people studying computer science or computer engineering get a strong background in mathematics as well as specific computer programming courses. If you want to pursue computer engineering and technology it would be good to learn a couple of computer programming languages such as Visual Basic and Visual C++. Other good courses to take include office applications such as word processors, spreadsheets, databases and presentation and graphics packages.

Don't let computers scare you. They are dumb machines. If people don't program them correctly they won't be able to use them as the tools they are intended to be.

Mathematics Trick:

This is a clever little mathematical trick. The bigger question is "Why does it work?" After trying it out, see if you can figure out how and why it works.

• Pick any three digits from the digits 0 through 9.

• Add 4 to your first choice and multiply it by 10.

• Add your second choice to this product, and multiply this by 10.

• To this product add your third choice.

• Subtract 400.

• Your final answer should have the three digits you picked in the same exact order, for example, I picked 6, 2 and 1:

• 6, 2, 1

• 6 + 4 = 10, 10 x 10 = 100 (6 was my first number)

• 2 + 100 = 102, 102 x 10 = 1020 (2 was my second number)

• 1020 + 1 = 1021 (1 was my third number)

• 1021 - 400 = 621 (621 is the same order as my picks of 6, 2, and 1)

Why? Try your own three digits and see what happens!
