Let's roll up our sleeves and solve this. We have 751 and we're going to multiply it by 13, essentially adding 751 to itself 13 times.
Step 1: 0 + 751 = 751
Step 2: 751 + 751 = 1502
Step 3: 1502 + 751 = 2253
Step 4: 2253 + 751 = 3004
Step 5: 3004 + 751 = 3755
Step 6: 3755 + 751 = 4506
Step 7: 4506 + 751 = 5257
Step 8: 5257 + 751 = 6008
Step 9: 6008 + 751 = 6759
Step 10: 6759 + 751 = 7510
Step 11: 7510 + 751 = 8261
Step 12: 8261 + 751 = 9012
Step 13: 9012 + 751 = 9763

So, 751*13 = 9763
