Lesson 55:
*FYI...To find the average of a set of numbers-->
add them up and divide by the number of numbers!
***If you are given what the average is and have to find one of the
missing numbers in the set of data...you have to work backwards...
--MULTIPLY the average by how many numbers in the set of data...
--ADD the numbers you HAVE been given...
--SUBTRACT the sum from the product!
