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 negative0.07=7×10−20.02=2×10−2(0.07×0.02)=7×10−2×2×10−2(0.07×0.02)÷14=7×10−2×2×10−2÷147 goes into 14, 2 times and 2 goes into itself 17×10−2×2×10−2÷14=1×10−2×1×10−2/11×10−2×1×10−2/1=1×10−2×10−2Applying am×an=am+n⇒1×10−2×10−2=1×10−2+−2=1×10−4Now change the whole number ×10a format back to decimalSince 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
