Without delay, let's solve this. We've got 982 and we will be multiplying it by 20, that is, adding 982 to itself 20 times.
Step 1: 0 + 982 = 982
Step 2: 982 + 982 = 1964
Step 3: 1964 + 982 = 2946
Step 4: 2946 + 982 = 3928
Step 5: 3928 + 982 = 4910
Step 6: 4910 + 982 = 5892
Step 7: 5892 + 982 = 6874
Step 8: 6874 + 982 = 7856
Step 9: 7856 + 982 = 8838
Step 10: 8838 + 982 = 9820
Step 11: 9820 + 982 = 10802
Step 12: 10802 + 982 = 11784
Step 13: 11784 + 982 = 12766
Step 14: 12766 + 982 = 13748
Step 15: 13748 + 982 = 14730
Step 16: 14730 + 982 = 15712
Step 17: 15712 + 982 = 16694
Step 18: 16694 + 982 = 17676
Step 19: 17676 + 982 = 18658
Step 20: 18658 + 982 = 19640

So, 982*20 = 19640
