Let's roll up our sleeves and solve this. We have 750 and we're going to multiply it by 53, essentially adding 750 to itself 53 times.
Step 1: 0 + 750 = 750
Step 2: 750 + 750 = 1500
Step 3: 1500 + 750 = 2250
Step 4: 2250 + 750 = 3000
Step 5: 3000 + 750 = 3750
Step 6: 3750 + 750 = 4500
Step 7: 4500 + 750 = 5250
Step 8: 5250 + 750 = 6000
Step 9: 6000 + 750 = 6750
Step 10: 6750 + 750 = 7500
Step 11: 7500 + 750 = 8250
Step 12: 8250 + 750 = 9000
Step 13: 9000 + 750 = 9750
Step 14: 9750 + 750 = 10500
Step 15: 10500 + 750 = 11250
Step 16: 11250 + 750 = 12000
Step 17: 12000 + 750 = 12750
Step 18: 12750 + 750 = 13500
Step 19: 13500 + 750 = 14250
Step 20: 14250 + 750 = 15000
Step 21: 15000 + 750 = 15750
Step 22: 15750 + 750 = 16500
Step 23: 16500 + 750 = 17250
Step 24: 17250 + 750 = 18000
Step 25: 18000 + 750 = 18750
Step 26: 18750 + 750 = 19500
Step 27: 19500 + 750 = 20250
Step 28: 20250 + 750 = 21000
Step 29: 21000 + 750 = 21750
Step 30: 21750 + 750 = 22500
Step 31: 22500 + 750 = 23250
Step 32: 23250 + 750 = 24000
Step 33: 24000 + 750 = 24750
Step 34: 24750 + 750 = 25500
Step 35: 25500 + 750 = 26250
Step 36: 26250 + 750 = 27000
Step 37: 27000 + 750 = 27750
Step 38: 27750 + 750 = 28500
Step 39: 28500 + 750 = 29250
Step 40: 29250 + 750 = 30000
Step 41: 30000 + 750 = 30750
Step 42: 30750 + 750 = 31500
Step 43: 31500 + 750 = 32250
Step 44: 32250 + 750 = 33000
Step 45: 33000 + 750 = 33750
Step 46: 33750 + 750 = 34500
Step 47: 34500 + 750 = 35250
Step 48: 35250 + 750 = 36000
Step 49: 36000 + 750 = 36750
Step 50: 36750 + 750 = 37500
Step 51: 37500 + 750 = 38250
Step 52: 38250 + 750 = 39000
Step 53: 39000 + 750 = 39750

So, 750*53 = 39750
