GED Math: adding fractions with common denominator

To add a fraction, express each fraction with a common denominator. Once each fraction has the same denominator, add the numerators and simplify.

Pascal's Triangle

An interesting number pattern is Pascal's Triangle. It was named after Blaise Pascal, a famous French Mathenatician and Philosopher.

Pascal's Triangle is included in the GED Math Practice tests and may appear in an "official" GED test. Therefore, it is importatant that GED students understand what the pattern is. I know that for myself, each time I see it, I have to THINK about the pattern.

Once you know what the pattern is, it is easy to continue the pattern.

Each number is just the two numbers above it, added together.

Now that I know the pattern..... I won't forget it!
