Let's roll up our sleeves and solve this. We have 653 and we're going to multiply it by 7, essentially adding 653 to itself 7 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

So, 653*7 = 4571
