OK, let's crack this. We're given 792 and our task is to multiply it by 8. Essentially, we'll be adding 792 to itself 8 times.
Step 1: 0 + 792 = 792
Step 2: 792 + 792 = 1584
Step 3: 1584 + 792 = 2376
Step 4: 2376 + 792 = 3168
Step 5: 3168 + 792 = 3960
Step 6: 3960 + 792 = 4752
Step 7: 4752 + 792 = 5544
Step 8: 5544 + 792 = 6336

So, 792*8 = 6336
