Let's roll up our sleeves and solve this. We have 732 and we're going to multiply it by 20, essentially adding 732 to itself 20 times.
Step 1: 0 + 732 = 732
Step 2: 732 + 732 = 1464
Step 3: 1464 + 732 = 2196
Step 4: 2196 + 732 = 2928
Step 5: 2928 + 732 = 3660
Step 6: 3660 + 732 = 4392
Step 7: 4392 + 732 = 5124
Step 8: 5124 + 732 = 5856
Step 9: 5856 + 732 = 6588
Step 10: 6588 + 732 = 7320
Step 11: 7320 + 732 = 8052
Step 12: 8052 + 732 = 8784
Step 13: 8784 + 732 = 9516
Step 14: 9516 + 732 = 10248
Step 15: 10248 + 732 = 10980
Step 16: 10980 + 732 = 11712
Step 17: 11712 + 732 = 12444
Step 18: 12444 + 732 = 13176
Step 19: 13176 + 732 = 13908
Step 20: 13908 + 732 = 14640

So, 732*20 = 14640
