What does how much means in math?

Answer 1

The concept of a mean is simple. If you are looking at a series of 3 numbers, lets just say 2, 7, & 9, and you have to find the mean, here's how:

1. Add up all of the numbers, (2+7+9=18)
2. Divide by the number of numbers (In this case the number of numbers is 3, so you have to divide by 3. So 18 ÷ 3 = 6, so the mean is six.)
