There are two operations you need to do for multiplications. First multiply the smallest digit, bring down the (one) and put up the (ten). Then multiply the next digit and add this result to the (ten) you brought up.
For example 45 x 3 = 135
where 5 x 3 = 15 (bring down the 5 and put up 10 above 40)
then 4(0) x 3 = 12(0)
Add the 1(0) to 12(0) to get 13(0), which you place next to 5, and get the result of 135.
