Let's get this math done. We have 350 and we're going to multiply it by 22. This is the same as taking 350 and adding it to itself 22 times.
Step 1: 0 + 350 = 350
Step 2: 350 + 350 = 700
Step 3: 700 + 350 = 1050
Step 4: 1050 + 350 = 1400
Step 5: 1400 + 350 = 1750
Step 6: 1750 + 350 = 2100
Step 7: 2100 + 350 = 2450
Step 8: 2450 + 350 = 2800
Step 9: 2800 + 350 = 3150
Step 10: 3150 + 350 = 3500
Step 11: 3500 + 350 = 3850
Step 12: 3850 + 350 = 4200
Step 13: 4200 + 350 = 4550
Step 14: 4550 + 350 = 4900
Step 15: 4900 + 350 = 5250
Step 16: 5250 + 350 = 5600
Step 17: 5600 + 350 = 5950
Step 18: 5950 + 350 = 6300
Step 19: 6300 + 350 = 6650
Step 20: 6650 + 350 = 7000
Step 21: 7000 + 350 = 7350
Step 22: 7350 + 350 = 7700

So, 350*22 = 7700
