OK, let's work through this together. We're starting with 747 and we're going to multiply it by 7, which means we add 747 to itself 7 times.
Step 1: 0 + 747 = 747
Step 2: 747 + 747 = 1494
Step 3: 1494 + 747 = 2241
Step 4: 2241 + 747 = 2988
Step 5: 2988 + 747 = 3735
Step 6: 3735 + 747 = 4482
Step 7: 4482 + 747 = 5229

So, 747*7 = 5229
