Without delay, let's solve this. We've got 270 and we will be multiplying it by 23, that is, adding 270 to itself 23 times.
Step 1: 0 + 270 = 270
Step 2: 270 + 270 = 540
Step 3: 540 + 270 = 810
Step 4: 810 + 270 = 1080
Step 5: 1080 + 270 = 1350
Step 6: 1350 + 270 = 1620
Step 7: 1620 + 270 = 1890
Step 8: 1890 + 270 = 2160
Step 9: 2160 + 270 = 2430
Step 10: 2430 + 270 = 2700
Step 11: 2700 + 270 = 2970
Step 12: 2970 + 270 = 3240
Step 13: 3240 + 270 = 3510
Step 14: 3510 + 270 = 3780
Step 15: 3780 + 270 = 4050
Step 16: 4050 + 270 = 4320
Step 17: 4320 + 270 = 4590
Step 18: 4590 + 270 = 4860
Step 19: 4860 + 270 = 5130
Step 20: 5130 + 270 = 5400
Step 21: 5400 + 270 = 5670
Step 22: 5670 + 270 = 5940
Step 23: 5940 + 270 = 6210

So, 270*23 = 6210
