Let's roll up our sleeves and solve this. We have 200 and we're going to multiply it by 52, essentially adding 200 to itself 52 times.
Step 1: 0 + 200 = 200
Step 2: 200 + 200 = 400
Step 3: 400 + 200 = 600
Step 4: 600 + 200 = 800
Step 5: 800 + 200 = 1000
Step 6: 1000 + 200 = 1200
Step 7: 1200 + 200 = 1400
Step 8: 1400 + 200 = 1600
Step 9: 1600 + 200 = 1800
Step 10: 1800 + 200 = 2000
Step 11: 2000 + 200 = 2200
Step 12: 2200 + 200 = 2400
Step 13: 2400 + 200 = 2600
Step 14: 2600 + 200 = 2800
Step 15: 2800 + 200 = 3000
Step 16: 3000 + 200 = 3200
Step 17: 3200 + 200 = 3400
Step 18: 3400 + 200 = 3600
Step 19: 3600 + 200 = 3800
Step 20: 3800 + 200 = 4000
Step 21: 4000 + 200 = 4200
Step 22: 4200 + 200 = 4400
Step 23: 4400 + 200 = 4600
Step 24: 4600 + 200 = 4800
Step 25: 4800 + 200 = 5000
Step 26: 5000 + 200 = 5200
Step 27: 5200 + 200 = 5400
Step 28: 5400 + 200 = 5600
Step 29: 5600 + 200 = 5800
Step 30: 5800 + 200 = 6000
Step 31: 6000 + 200 = 6200
Step 32: 6200 + 200 = 6400
Step 33: 6400 + 200 = 6600
Step 34: 6600 + 200 = 6800
Step 35: 6800 + 200 = 7000
Step 36: 7000 + 200 = 7200
Step 37: 7200 + 200 = 7400
Step 38: 7400 + 200 = 7600
Step 39: 7600 + 200 = 7800
Step 40: 7800 + 200 = 8000
Step 41: 8000 + 200 = 8200
Step 42: 8200 + 200 = 8400
Step 43: 8400 + 200 = 8600
Step 44: 8600 + 200 = 8800
Step 45: 8800 + 200 = 9000
Step 46: 9000 + 200 = 9200
Step 47: 9200 + 200 = 9400
Step 48: 9400 + 200 = 9600
Step 49: 9600 + 200 = 9800
Step 50: 9800 + 200 = 10000
Step 51: 10000 + 200 = 10200
Step 52: 10200 + 200 = 10400

So, 200*52 = 10400
