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
