Mean The mean of a group of numbers is the same thing as the average. It's weird to define "average" in words, but really easy to show what it is. Look at this list of numbers: 3, 6, 13, 4, 9... Add them up and we get 35... Now, divide by how many numbers there are. There are five numbers, so divide 35 by 5... We get 7 and that's the average of this list of numbers. Notice that some of the numbers are above 7 and some are below. 

Median The median is the middle number of a group. Example: Here's a list of numbers: 2, 8, 5, 9, 12, 11, 1 Arrange them in order: 1, 2, 5, 8, 9, 11, 12 Count in from the front and the back to find the one that's in the middle... The median is 8. 


Milligram A milligram is one 1000th of a gram. 

Millimeter A millimeter is one 1000th of a meter. 

Millisecond A millisecond is one 1000th of a second and that's quick, baby! 

Minuend The minuend is the number you are subtracting FROM: 8  5 = 3 For more info, check out my Subtraction Lessons. 



Mode In a list of numbers (like exam results), the mode is the number that occurs the most. Example: 4, 5, 7, 8, 9, 4, 5, 4 The mode is 4. 

Monomial A monomial is a polynomial with just one term. For more info, check out my Polynomial lessons. 

Multiple A multiple is a number that is the product of a given number and some other number. Examples: 12 is a multiple of 4 (since 4 x 3 = 12). 100 is a multiple of 5 (since 5 x 20 = 100). 

Multiplicity When a root (or zero) occurs more that once in a polynomial, we say that the root has a multiplicity of 2 (if the root occurs twice). For more info and examples, check out my lesson on Multiplicities.
