Basic Math Examples

$8$ , $44 \cdot 10^{6}$

Step 1

Move the decimal point in $44$ to the left by $1$ place and increase the power of $10^{6}$ by $1$ .

$8, 4.4 \cdot 10^{7}$

Step 2

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

$\frac{8 + 4.4 \cdot 10^{7}}{2}$

Step 3

Convert $8$ to scientific notation.

$\frac{8 \cdot 10^{0} + 4.4 \cdot 10^{7}}{2}$

Step 4

Move the decimal point in $8$ to the left by $7$ places and increase the power of $10^{0}$ by $7$ .

$\frac{0.0000008 \cdot 10^{7} + 4.4 \cdot 10^{7}}{2}$

Step 5

Factor $10^{7}$ out of $0.0000008 \cdot 10^{7} + 4.4 \cdot 10^{7}$ .

$\frac{(0.0000008 + 4.4) \cdot 10^{7}}{2}$

Step 6

Add $0.0000008$ and $4.4$ .

$\frac{4.4000008 \cdot 10^{7}}{2}$
