A complex fraction is a fraction in which the numerator, denominator, or both also contain a fraction. For this reason complex fractions are sometimes referred to as "stacked fractions". Simplifying complex fractions can be easy or difficult, depending on how many numbers are in the numerator and denominator, whether one of the numbers is a variable, or the complexity of the variable number.

Factors of a number are numbers that can be multiplied to get that number. Another way of looking at it is that every number is the product of multiple factors. Learning how to factor – that is, breaking down a number into its component factors – is a mathematical skill that is used not only in basic arithmetic but also in algebra, calculus, and others.

A parallel line is two lines in a plane that will never meet (meaning that the two lines will not intersect each other even if they are extended indefinitely). The key feature of parallel lines is that they have exactly the same slope. The slope of a line is defined as the vertical increase (change in the Y coordinate) to the horizontal increase (change in the coordinates of the X axis) of a line, in other words, the slope is the slope of a line.
