Let's get this math done. We have 798 and we're going to multiply it by 8. This is the same as taking 798 and adding it to itself 8 times.
Step 1: 0 + 798 = 798
Step 2: 798 + 798 = 1596
Step 3: 1596 + 798 = 2394
Step 4: 2394 + 798 = 3192
Step 5: 3192 + 798 = 3990
Step 6: 3990 + 798 = 4788
Step 7: 4788 + 798 = 5586
Step 8: 5586 + 798 = 6384

So, 798*8 = 6384
