Sure thing, let's get straight to it. We start with 653 and we're going to multiply it by 24, which means adding 653 to itself 24 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
Step 13: 7836 + 653 = 8489
Step 14: 8489 + 653 = 9142
Step 15: 9142 + 653 = 9795
Step 16: 9795 + 653 = 10448
Step 17: 10448 + 653 = 11101
Step 18: 11101 + 653 = 11754
Step 19: 11754 + 653 = 12407
Step 20: 12407 + 653 = 13060
Step 21: 13060 + 653 = 13713
Step 22: 13713 + 653 = 14366
Step 23: 14366 + 653 = 15019
Step 24: 15019 + 653 = 15672

So, 653*24 = 15672
