Convert each item to standard form before addition.

To convert scientific form to standard form move the decimal point the number of digits given by the exponent, if positive to the right, if negative to the left; if the digits run out insert zeros. If no decimal point is visible it is "hiding" after the last digit.

8 x 10¹ = 80

3 × 10^-3 = 0.003

→ 8 × 10¹ + 3 × 10^-3 = 80 + 0.003 = 80.003

### How do you put numbers in standard form?

Standard form is a way of writing large numbers or very small
number easily. For example, if we have 5000, we will write it as 5
* 103 in standard form. The exponent of 3 represents how many 0's
there are in the number.
An example of writing a very small number is .0005
We write it as 5 * 10-4 in standard form. The negative sign in
the exponent tells us that the number is a decimal. We write -4
because we've moved the number (5) 4 places to the right.
