OK, let's work through this together. We're starting with 626 and we're going to multiply it by 8, which means we add 626 to itself 8 times.
Step 1: 0 + 626 = 626
Step 2: 626 + 626 = 1252
Step 3: 1252 + 626 = 1878
Step 4: 1878 + 626 = 2504
Step 5: 2504 + 626 = 3130
Step 6: 3130 + 626 = 3756
Step 7: 3756 + 626 = 4382
Step 8: 4382 + 626 = 5008

So, 626*8 = 5008
