Find the Average [-2,2]

$[- 2, 2]$

Step 1

The mean of a set of numbers is the sum divided by the number of terms.

$\frac{- 2 + 2}{2}$

Step 2

Cancel the common factor of $- 2 + 2$ and $2$ .

Factor $2$ out of $- 2$ .

$\frac{2 \cdot - 1 + 2}{2}$

Factor $2$ out of $2$ .

$\frac{2 \cdot - 1 + 2 \cdot 1}{2}$

Factor $2$ out of $2 \cdot - 1 + 2 \cdot 1$ .

$\frac{2 \cdot (- 1 + 1)}{2}$

Cancel the common factors.

Factor $2$ out of $2$ .

$\frac{2 \cdot (- 1 + 1)}{2 (1)}$

Cancel the common factor.

$\frac{2 \cdot (- 1 + 1)}{2 \cdot 1}$

Rewrite the expression.

$\frac{- 1 + 1}{1}$

Divide $- 1 + 1$ by $1$ .

$- 1 + 1$

Step 3

Add $- 1$ and $1$ .

$0$
