Let's get this math done. We have 545 and we're going to multiply it by 8. This is the same as taking 545 and adding it to itself 8 times.
Step 1: 0 + 545 = 545
Step 2: 545 + 545 = 1090
Step 3: 1090 + 545 = 1635
Step 4: 1635 + 545 = 2180
Step 5: 2180 + 545 = 2725
Step 6: 2725 + 545 = 3270
Step 7: 3270 + 545 = 3815
Step 8: 3815 + 545 = 4360

So, 545*8 = 4360
