OK, let's work through this together. We're starting with 552 and we're going to multiply it by 22, which means we add 552 to itself 22 times.
Step 1: 0 + 552 = 552
Step 2: 552 + 552 = 1104
Step 3: 1104 + 552 = 1656
Step 4: 1656 + 552 = 2208
Step 5: 2208 + 552 = 2760
Step 6: 2760 + 552 = 3312
Step 7: 3312 + 552 = 3864
Step 8: 3864 + 552 = 4416
Step 9: 4416 + 552 = 4968
Step 10: 4968 + 552 = 5520
Step 11: 5520 + 552 = 6072
Step 12: 6072 + 552 = 6624
Step 13: 6624 + 552 = 7176
Step 14: 7176 + 552 = 7728
Step 15: 7728 + 552 = 8280
Step 16: 8280 + 552 = 8832
Step 17: 8832 + 552 = 9384
Step 18: 9384 + 552 = 9936
Step 19: 9936 + 552 = 10488
Step 20: 10488 + 552 = 11040
Step 21: 11040 + 552 = 11592
Step 22: 11592 + 552 = 12144

So, 552*22 = 12144
