Without delay, let's solve this. We've got 220 and we will be multiplying it by 28, that is, adding 220 to itself 28 times.
Step 1: 0 + 220 = 220
Step 2: 220 + 220 = 440
Step 3: 440 + 220 = 660
Step 4: 660 + 220 = 880
Step 5: 880 + 220 = 1100
Step 6: 1100 + 220 = 1320
Step 7: 1320 + 220 = 1540
Step 8: 1540 + 220 = 1760
Step 9: 1760 + 220 = 1980
Step 10: 1980 + 220 = 2200
Step 11: 2200 + 220 = 2420
Step 12: 2420 + 220 = 2640
Step 13: 2640 + 220 = 2860
Step 14: 2860 + 220 = 3080
Step 15: 3080 + 220 = 3300
Step 16: 3300 + 220 = 3520
Step 17: 3520 + 220 = 3740
Step 18: 3740 + 220 = 3960
Step 19: 3960 + 220 = 4180
Step 20: 4180 + 220 = 4400
Step 21: 4400 + 220 = 4620
Step 22: 4620 + 220 = 4840
Step 23: 4840 + 220 = 5060
Step 24: 5060 + 220 = 5280
Step 25: 5280 + 220 = 5500
Step 26: 5500 + 220 = 5720
Step 27: 5720 + 220 = 5940
Step 28: 5940 + 220 = 6160

So, 220*28 = 6160
