Let's get this math done. We have 560 and we're going to multiply it by 7. This is the same as taking 560 and adding it to itself 7 times.
Step 1: 0 + 560 = 560
Step 2: 560 + 560 = 1120
Step 3: 1120 + 560 = 1680
Step 4: 1680 + 560 = 2240
Step 5: 2240 + 560 = 2800
Step 6: 2800 + 560 = 3360
Step 7: 3360 + 560 = 3920

So, 560*7 = 3920
