OK, let's crack this. We're given 452 and our task is to multiply it by 36. Essentially, we'll be adding 452 to itself 36 times.
Step 1: 0 + 452 = 452
Step 2: 452 + 452 = 904
Step 3: 904 + 452 = 1356
Step 4: 1356 + 452 = 1808
Step 5: 1808 + 452 = 2260
Step 6: 2260 + 452 = 2712
Step 7: 2712 + 452 = 3164
Step 8: 3164 + 452 = 3616
Step 9: 3616 + 452 = 4068
Step 10: 4068 + 452 = 4520
Step 11: 4520 + 452 = 4972
Step 12: 4972 + 452 = 5424
Step 13: 5424 + 452 = 5876
Step 14: 5876 + 452 = 6328
Step 15: 6328 + 452 = 6780
Step 16: 6780 + 452 = 7232
Step 17: 7232 + 452 = 7684
Step 18: 7684 + 452 = 8136
Step 19: 8136 + 452 = 8588
Step 20: 8588 + 452 = 9040
Step 21: 9040 + 452 = 9492
Step 22: 9492 + 452 = 9944
Step 23: 9944 + 452 = 10396
Step 24: 10396 + 452 = 10848
Step 25: 10848 + 452 = 11300
Step 26: 11300 + 452 = 11752
Step 27: 11752 + 452 = 12204
Step 28: 12204 + 452 = 12656
Step 29: 12656 + 452 = 13108
Step 30: 13108 + 452 = 13560
Step 31: 13560 + 452 = 14012
Step 32: 14012 + 452 = 14464
Step 33: 14464 + 452 = 14916
Step 34: 14916 + 452 = 15368
Step 35: 15368 + 452 = 15820
Step 36: 15820 + 452 = 16272

So, 452*36 = 16272
