Let's roll up our sleeves and solve this. We have 740 and we're going to multiply it by 17, essentially adding 740 to itself 17 times.
Step 1: 0 + 740 = 740
Step 2: 740 + 740 = 1480
Step 3: 1480 + 740 = 2220
Step 4: 2220 + 740 = 2960
Step 5: 2960 + 740 = 3700
Step 6: 3700 + 740 = 4440
Step 7: 4440 + 740 = 5180
Step 8: 5180 + 740 = 5920
Step 9: 5920 + 740 = 6660
Step 10: 6660 + 740 = 7400
Step 11: 7400 + 740 = 8140
Step 12: 8140 + 740 = 8880
Step 13: 8880 + 740 = 9620
Step 14: 9620 + 740 = 10360
Step 15: 10360 + 740 = 11100
Step 16: 11100 + 740 = 11840
Step 17: 11840 + 740 = 12580

So, 740*17 = 12580
