# ARITHMETIC GLOSSARY

Mr. X is glad to provide video presentations of hundreds of arithmetic glossary terms. The arithmetic glossary is part of a complete math glossary available free of charge on the website. All arithmetic glossary terms are provided free of charge to all users.
Title Description
Radical A root symbol or the root itself is sometimes termed a Radical.
Radicand A number taken to a root is a Radicand; the number under a root sign.
It is the distance from the center of a circle to any point on the circle.
Range We may speak of a Range of values as simply the difference between high and low values of a data set.
More specifically, the values generated by the input of domain values into a function map into the Range of values of the function.
Ratio Sometimes Ratio is meant to state a constant proportion.
More generally, the Ratio of two real values is the quotient of one number divided by the other.
Rational A Rational number can be expressed as the ratio of two integers.
When expressed as a decimal, a Rational number will either repeat or terminate (with repeating zeros).
Rational Expression Mathematical statements written as fractions with a numerator and a denominator are often termed Rational Expressions.
Ray A set of collinear points, a Ray has an endpoint and proceeds infinitely far in a single direction.
Real Number Depicted on the Real Number line, such a value is either less than, equal to, or greater than every other real value.
Reciprocal Every nonzero real value has a Reciprocal.
A number and its Reciprocal multiply to one.
We may find a Reciprocal of a number by dividing it into 1.
Rectangle A quadrilateral with many special properties, including all those of a parallelogram, and then some.
Relatively Prime Two integers with no common factors other than one are said to be Relatively Prime.
Remainder When a divisor does not divide evenly into the dividend, we have a Remainder.
Revolutions per Minute Abbreviated "rpm," it conveys the number of complete circular rotations that occur every 60 seconds at some constant rate of revolution.
Right Angle An angle of 90 degrees or pi/2 radians.
Perpendicular lines meet at Right Angles.
Right Triangle A triangle with a right angle.
Root (Number) The Root of a given Number is the value that raised to the power of the root returns the given number.
Rounding Not exactly truncating, rounding involves reduction in the precision of a value to approximate that value to some exact value with less precision.
