Sure thing! We've got 743 and we're gonna multiply it by 9. That's the same as adding 743 to itself 9 times.
Step 1: 0 + 743 = 743
Step 2: 743 + 743 = 1486
Step 3: 1486 + 743 = 2229
Step 4: 2229 + 743 = 2972
Step 5: 2972 + 743 = 3715
Step 6: 3715 + 743 = 4458
Step 7: 4458 + 743 = 5201
Step 8: 5201 + 743 = 5944
Step 9: 5944 + 743 = 6687

So, 743*9 = 6687
