Let's get this math done. We have 740 and we're going to multiply it by 24. This is the same as taking 740 and adding it to itself 24 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
Step 18: 12580 + 740 = 13320
Step 19: 13320 + 740 = 14060
Step 20: 14060 + 740 = 14800
Step 21: 14800 + 740 = 15540
Step 22: 15540 + 740 = 16280
Step 23: 16280 + 740 = 17020
Step 24: 17020 + 740 = 17760

So, 740*24 = 17760
