Let's get this math done. We have 353 and we're going to multiply it by 8. This is the same as taking 353 and adding it to itself 8 times.
Step 1: 0 + 353 = 353
Step 2: 353 + 353 = 706
Step 3: 706 + 353 = 1059
Step 4: 1059 + 353 = 1412
Step 5: 1412 + 353 = 1765
Step 6: 1765 + 353 = 2118
Step 7: 2118 + 353 = 2471
Step 8: 2471 + 353 = 2824

So, 353*8 = 2824
