OK, let's crack this. We're given 270 and our task is to multiply it by 55. Essentially, we'll be adding 270 to itself 55 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
Step 24: 6210 + 270 = 6480
Step 25: 6480 + 270 = 6750
Step 26: 6750 + 270 = 7020
Step 27: 7020 + 270 = 7290
Step 28: 7290 + 270 = 7560
Step 29: 7560 + 270 = 7830
Step 30: 7830 + 270 = 8100
Step 31: 8100 + 270 = 8370
Step 32: 8370 + 270 = 8640
Step 33: 8640 + 270 = 8910
Step 34: 8910 + 270 = 9180
Step 35: 9180 + 270 = 9450
Step 36: 9450 + 270 = 9720
Step 37: 9720 + 270 = 9990
Step 38: 9990 + 270 = 10260
Step 39: 10260 + 270 = 10530
Step 40: 10530 + 270 = 10800
Step 41: 10800 + 270 = 11070
Step 42: 11070 + 270 = 11340
Step 43: 11340 + 270 = 11610
Step 44: 11610 + 270 = 11880
Step 45: 11880 + 270 = 12150
Step 46: 12150 + 270 = 12420
Step 47: 12420 + 270 = 12690
Step 48: 12690 + 270 = 12960
Step 49: 12960 + 270 = 13230
Step 50: 13230 + 270 = 13500
Step 51: 13500 + 270 = 13770
Step 52: 13770 + 270 = 14040
Step 53: 14040 + 270 = 14310
Step 54: 14310 + 270 = 14580
Step 55: 14580 + 270 = 14850

So, 270*55 = 14850
