Let's roll up our sleeves and solve this. We have 736 and we're going to multiply it by 15, essentially adding 736 to itself 15 times.
Step 1: 0 + 736 = 736
Step 2: 736 + 736 = 1472
Step 3: 1472 + 736 = 2208
Step 4: 2208 + 736 = 2944
Step 5: 2944 + 736 = 3680
Step 6: 3680 + 736 = 4416
Step 7: 4416 + 736 = 5152
Step 8: 5152 + 736 = 5888
Step 9: 5888 + 736 = 6624
Step 10: 6624 + 736 = 7360
Step 11: 7360 + 736 = 8096
Step 12: 8096 + 736 = 8832
Step 13: 8832 + 736 = 9568
Step 14: 9568 + 736 = 10304
Step 15: 10304 + 736 = 11040

So, 736*15 = 11040
