Let's roll up our sleeves and solve this. We have 122 and we're going to multiply it by 30, essentially adding 122 to itself 30 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
Step 21: 2440 + 122 = 2562
Step 22: 2562 + 122 = 2684
Step 23: 2684 + 122 = 2806
Step 24: 2806 + 122 = 2928
Step 25: 2928 + 122 = 3050
Step 26: 3050 + 122 = 3172
Step 27: 3172 + 122 = 3294
Step 28: 3294 + 122 = 3416
Step 29: 3416 + 122 = 3538
Step 30: 3538 + 122 = 3660

So, 122*30 = 3660
