Let's get this math done. We have 536 and we're going to multiply it by 12. This is the same as taking 536 and adding it to itself 12 times.
Step 1: 0 + 536 = 536
Step 2: 536 + 536 = 1072
Step 3: 1072 + 536 = 1608
Step 4: 1608 + 536 = 2144
Step 5: 2144 + 536 = 2680
Step 6: 2680 + 536 = 3216
Step 7: 3216 + 536 = 3752
Step 8: 3752 + 536 = 4288
Step 9: 4288 + 536 = 4824
Step 10: 4824 + 536 = 5360
Step 11: 5360 + 536 = 5896
Step 12: 5896 + 536 = 6432

So, 536*12 = 6432
