Basic Math Examples

$2$ , $9 \cdot 10^{- 12}$

Step 1

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

$\frac{2 + 9 \cdot 10^{- 12}}{2}$

Step 2

Convert $2$ to scientific notation.

$\frac{2 \cdot 10^{0} + 9 \cdot 10^{- 12}}{2}$

Step 3

Move the decimal point in $9$ to the left by $12$ places and increase the power of $10^{- 12}$ by $12$ .

$\frac{2 \cdot 10^{0} + 0 \cdot 10^{0}}{2}$

Step 4

Factor $10^{0}$ out of $2 \cdot 10^{0} + 0 \cdot 10^{0}$ .

$\frac{(2 + 0) \cdot 10^{0}}{2}$

Step 5

Add $2$ and $0$ .

$\frac{2 \cdot 10^{0}}{2}$

Step 6

Divide using scientific notation.

Step 6.1

Group coefficients together and exponents together to divide numbers in scientific notation.

$(\frac{2}{2}) (\frac{10^{0}}{1})$

Step 6.2

Divide $2$ by $2$ .

$1 \frac{10^{0}}{1}$

Step 6.3

Divide $10^{0}$ by $1$ .

$1 \cdot 10^{0}$

Step 7

Convert $1 \cdot 10^{0}$ from scientific notation.

$1$

Step 8

The mean should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.
