More words on math dictionary-r are as follows:
To multiply a number by itself a certain amount of time. Example: 10 raise to the power 5 = 10⁵ = 10x10x10x10x10 = 100000.
Selecting an item from the given set of items without any order. That is like drawing a number from a hat.

Ratio that tells how one number is related to other number. Ratio of 'a' and 'b' is written as a/b or a:b
Rational function A ratio of two polynomial functions.
Let A and B be two given points. Let P be a point on the line segment AB or AB produced. The P divides the line segment AB in to two segments AP and PB. the lengths of AP and PB are AP and PB. These lengths are in some ratio m:n or that is AP:PB =m:n or AP/PB =m/n. If P lies inside AB, we say that P divides AB internally in the ratio m:n. If P lies outside AB, that is P lies on AB produced, then we say P divides AB externally in the ratio m:n.
A line that has a starting point but no end point.
All the whole, rational and irrational numbers are called real numbers.
Multiplicative inverse of a number. One of two numbers whose product is 1. Example: Reciprocal of 2 is 1/2.
