Rational Numbers

Proper fractions always exist between zero and one on the number line.
Improper fractions are represented on the number line by first converting them into mixed fractions and then representing them on the number line.
Two rational numbers are considered opposites if they have the same distance from 0, but on different sides of 0.
Two rational numbers with the same denominator are compared by comparing their numerators. The number with the greater numerator is greater.
The sum of two fractions with the same denominator is calculated by adding their numerators and keeping the same denominator.
The product of two fractions is calculated by multiplying their numerators and multiplying their denominators.

Interest

The money that is borrowed or loaned is called the base (B).
The interest paid on the original principal during the whole interest periods is called compound interest.

Squaring and Cubing Numbers

Squaring a number is the process of multiplying a number by itself.
Cubing a number is the process of multiplying a number by itself three times.
