What does mean in math mean?

Answer 1

In Maths, the mean is the mean average; in other words, the average. To calculate the mean (average), you add the numbers you have together and then divide that total by the amount of numbers of had.

Example: I have 5, 12, 4, and 2. Calculate the mean

5+12+4+3=24

24 divided by 4=6

6 is your average, however not all questions will be this simple. Sometimes it gets all complicated and goes into decimals and then it gets nasty :D
