Let's roll up our sleeves and solve this. We have 700 and we're going to multiply it by 35, essentially adding 700 to itself 35 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
Step 25: 16800 + 700 = 17500
Step 26: 17500 + 700 = 18200
Step 27: 18200 + 700 = 18900
Step 28: 18900 + 700 = 19600
Step 29: 19600 + 700 = 20300
Step 30: 20300 + 700 = 21000
Step 31: 21000 + 700 = 21700
Step 32: 21700 + 700 = 22400
Step 33: 22400 + 700 = 23100
Step 34: 23100 + 700 = 23800
Step 35: 23800 + 700 = 24500

So, 700*35 = 24500
