Without delay, let's solve this. We've got 653 and we will be multiplying it by 12, that is, adding 653 to itself 12 times.
Step 1: 0 + 653 = 653
Step 2: 653 + 653 = 1306
Step 3: 1306 + 653 = 1959
Step 4: 1959 + 653 = 2612
Step 5: 2612 + 653 = 3265
Step 6: 3265 + 653 = 3918
Step 7: 3918 + 653 = 4571
Step 8: 4571 + 653 = 5224
Step 9: 5224 + 653 = 5877
Step 10: 5877 + 653 = 6530
Step 11: 6530 + 653 = 7183
Step 12: 7183 + 653 = 7836

So, 653*12 = 7836
