subtract the smallest from the biggest number in the data
adding all the numbers to find the total
the difference between two numbers on the scale
Includes all numbers

ORDER OF OPERATIONS
the order in which operations in an expression to be evaluated are carried out. 1. parentheses 2. exponets 3. multiplication and divison 4. addition and subtraction
a letter or other symbol that represents a number
a rate where the comparison is to one unit...example 99 cents per egg
numbers you say when you skip count. Multiples of 2 are: 2,4,6,8,...
the largest number of a set of data
The median of the upper half of a set of data.
replace, To put a number in place of a variable
The median of the lower half of data (box & whisker).
Numbers that are multiplied together to get a product ex. factors of 52 are 2, 4, 13, and 26
a ratio that compares a number to 100.
