Sure thing! We've got 122 and we're gonna multiply it by 20. That's the same as adding 122 to itself 20 times.
Step 1: 0 + 122 = 122
Step 2: 122 + 122 = 244
Step 3: 244 + 122 = 366
Step 4: 366 + 122 = 488
Step 5: 488 + 122 = 610
Step 6: 610 + 122 = 732
Step 7: 732 + 122 = 854
Step 8: 854 + 122 = 976
Step 9: 976 + 122 = 1098
Step 10: 1098 + 122 = 1220
Step 11: 1220 + 122 = 1342
Step 12: 1342 + 122 = 1464
Step 13: 1464 + 122 = 1586
Step 14: 1586 + 122 = 1708
Step 15: 1708 + 122 = 1830
Step 16: 1830 + 122 = 1952
Step 17: 1952 + 122 = 2074
Step 18: 2074 + 122 = 2196
Step 19: 2196 + 122 = 2318
Step 20: 2318 + 122 = 2440

So, 122*20 = 2440
