The rule for factors raised to the power n is: the right-hand side is the sum of n new fractions where the numerator of each fraction is the typical numerator for this type of factor in PFD, but ...


Fraction Rules. Below is a list of fraction basics as well as explanations for each rule. If the numerator remains the same for all fractions but the denominator gets larger, the actual value of the fraction gets smaller. This fraction rule is because of the fact that if the denominator increases then the whole is divided into more parts.

This allows, together with the above rules, to compare all possible fractions. Addition. The first rule of addition is that only like quantities can be added; for example, various quantities of quarters. Unlike quantities, such as adding thirds to quarters, must first be converted to like quantities as described below: Imagine a pocket ...


Algebra rules for combining fractions. These rules apply for both proper fractions and improper fractions. They apply for all rational expressions as well. Special note: Why is it OK to have 0 on top (in the numerator) and not on the bottom (in the denominator )? Consider for a moment what division means. The reason that is because 2·5 = 10.


General rules apply to addition when adding in columns, finding the sum of fractions, combining decimal numbers or in the use of negatives. You will want to know addition rules to build confidence and accuracy. When adding multiple digit numbers in columns, all the "ones" are in the right column, the "10s" to the left, then the "hundreds" and ...
