OK, let's crack this. We're given 436 and our task is to multiply it by 12. Essentially, we'll be adding 436 to itself 12 times.
Step 1: 0 + 436 = 436
Step 2: 436 + 436 = 872
Step 3: 872 + 436 = 1308
Step 4: 1308 + 436 = 1744
Step 5: 1744 + 436 = 2180
Step 6: 2180 + 436 = 2616
Step 7: 2616 + 436 = 3052
Step 8: 3052 + 436 = 3488
Step 9: 3488 + 436 = 3924
Step 10: 3924 + 436 = 4360
Step 11: 4360 + 436 = 4796
Step 12: 4796 + 436 = 5232

So, 436*12 = 5232
