Let's get this math done. We have 461 and we're going to multiply it by 20. This is the same as taking 461 and adding it to itself 20 times.
Step 1: 0 + 461 = 461
Step 2: 461 + 461 = 922
Step 3: 922 + 461 = 1383
Step 4: 1383 + 461 = 1844
Step 5: 1844 + 461 = 2305
Step 6: 2305 + 461 = 2766
Step 7: 2766 + 461 = 3227
Step 8: 3227 + 461 = 3688
Step 9: 3688 + 461 = 4149
Step 10: 4149 + 461 = 4610
Step 11: 4610 + 461 = 5071
Step 12: 5071 + 461 = 5532
Step 13: 5532 + 461 = 5993
Step 14: 5993 + 461 = 6454
Step 15: 6454 + 461 = 6915
Step 16: 6915 + 461 = 7376
Step 17: 7376 + 461 = 7837
Step 18: 7837 + 461 = 8298
Step 19: 8298 + 461 = 8759
Step 20: 8759 + 461 = 9220

So, 461*20 = 9220
