OK, let's crack this. We're given 700 and our task is to multiply it by 24. Essentially, we'll be adding 700 to itself 24 times.
Step 1: 0 + 700 = 700
Step 2: 700 + 700 = 1400
Step 3: 1400 + 700 = 2100
Step 4: 2100 + 700 = 2800
Step 5: 2800 + 700 = 3500
Step 6: 3500 + 700 = 4200
Step 7: 4200 + 700 = 4900
Step 8: 4900 + 700 = 5600
Step 9: 5600 + 700 = 6300
Step 10: 6300 + 700 = 7000
Step 11: 7000 + 700 = 7700
Step 12: 7700 + 700 = 8400
Step 13: 8400 + 700 = 9100
Step 14: 9100 + 700 = 9800
Step 15: 9800 + 700 = 10500
Step 16: 10500 + 700 = 11200
Step 17: 11200 + 700 = 11900
Step 18: 11900 + 700 = 12600
Step 19: 12600 + 700 = 13300
Step 20: 13300 + 700 = 14000
Step 21: 14000 + 700 = 14700
Step 22: 14700 + 700 = 15400
Step 23: 15400 + 700 = 16100
Step 24: 16100 + 700 = 16800

So, 700*24 = 16800
