expression
A variable or combination of variables, numbers, and symbols that represents a mathematical relationship.
fraction
A way of representing part of a whole or part of a group by telling the number of equal parts in the whole and the number of parts you are describing.
prime number
A whole number greater than 0 that has exactly two different factors, 1 and itself.
