Let's roll up our sleeves and solve this. We have 50 and we're going to multiply it by 33, essentially adding 50 to itself 33 times.
Step 1: 0 + 50 = 50
Step 2: 50 + 50 = 100
Step 3: 100 + 50 = 150
Step 4: 150 + 50 = 200
Step 5: 200 + 50 = 250
Step 6: 250 + 50 = 300
Step 7: 300 + 50 = 350
Step 8: 350 + 50 = 400
Step 9: 400 + 50 = 450
Step 10: 450 + 50 = 500
Step 11: 500 + 50 = 550
Step 12: 550 + 50 = 600
Step 13: 600 + 50 = 650
Step 14: 650 + 50 = 700
Step 15: 700 + 50 = 750
Step 16: 750 + 50 = 800
Step 17: 800 + 50 = 850
Step 18: 850 + 50 = 900
Step 19: 900 + 50 = 950
Step 20: 950 + 50 = 1000
Step 21: 1000 + 50 = 1050
Step 22: 1050 + 50 = 1100
Step 23: 1100 + 50 = 1150
Step 24: 1150 + 50 = 1200
Step 25: 1200 + 50 = 1250
Step 26: 1250 + 50 = 1300
Step 27: 1300 + 50 = 1350
Step 28: 1350 + 50 = 1400
Step 29: 1400 + 50 = 1450
Step 30: 1450 + 50 = 1500
Step 31: 1500 + 50 = 1550
Step 32: 1550 + 50 = 1600
Step 33: 1600 + 50 = 1650

So, 50*33 = 1650
