Change the decimals to the form whole number ×10a where a is the number of times you move the decimal point to get the whole number. If the decimal point is moved to the right, the sign is negative 0.07=7×10−2 0.02=2×10−2 ⇒(0.07×0.02)=7×10−2×2×10−2 (0.07×0.02)÷14=7×10−2×2×10−2÷14 7 goes into 14, 2 times and 2 goes into itself 1 7×10−2×2×10−2÷14=1×10−2×1×10−2∕1 1×10−2×1×10−2∕1=1×10−2×10−2 Applying am×an=am+n ⇒1×10−2×10−2=1×10−2+−2=1×10−4 Now change the whole number ×10a format back to decimal Since the power in 10−4 is negative 4 , you have to move the decimal point to the left four times 1=1.0 (Every number has .0 which is not written) 1.0×10−4=0.0001
