Let's get this math done. We have 435 and we're going to multiply it by 8. This is the same as taking 435 and adding it to itself 8 times.
Step 1: 0 + 435 = 435
Step 2: 435 + 435 = 870
Step 3: 870 + 435 = 1305
Step 4: 1305 + 435 = 1740
Step 5: 1740 + 435 = 2175
Step 6: 2175 + 435 = 2610
Step 7: 2610 + 435 = 3045
Step 8: 3045 + 435 = 3480

So, 435*8 = 3480
