Basic Math Examples

$2$ ,

$2 \cdot 10^{3}$

Step 1

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

$\frac{2 + 2 \cdot 10^{3}}{2}$

Step 2

Convert

$2$ to scientific notation.

$\frac{2 \cdot 10^{0} + 2 \cdot 10^{3}}{2}$

Step 3

Move the decimal point in

$2$ to the left by

$3$ places and increase the power of

$10^{0}$ by

$3$ .

$\frac{0.002 \cdot 10^{3} + 2 \cdot 10^{3}}{2}$

Step 4

Factor

$10^{3}$ out of

$0.002 \cdot 10^{3} + 2 \cdot 10^{3}$ .

$\frac{(0.002 + 2) \cdot 10^{3}}{2}$

Step 5

Add

$0.002$ and

$2$ .

$\frac{2.002 \cdot 10^{3}}{2}$
