Let's get this math done. We have 55 and we're going to multiply it by 51. This is the same as taking 55 and adding it to itself 51 times.
Step 1: 0 + 55 = 55
Step 2: 55 + 55 = 110
Step 3: 110 + 55 = 165
Step 4: 165 + 55 = 220
Step 5: 220 + 55 = 275
Step 6: 275 + 55 = 330
Step 7: 330 + 55 = 385
Step 8: 385 + 55 = 440
Step 9: 440 + 55 = 495
Step 10: 495 + 55 = 550
Step 11: 550 + 55 = 605
Step 12: 605 + 55 = 660
Step 13: 660 + 55 = 715
Step 14: 715 + 55 = 770
Step 15: 770 + 55 = 825
Step 16: 825 + 55 = 880
Step 17: 880 + 55 = 935
Step 18: 935 + 55 = 990
Step 19: 990 + 55 = 1045
Step 20: 1045 + 55 = 1100
Step 21: 1100 + 55 = 1155
Step 22: 1155 + 55 = 1210
Step 23: 1210 + 55 = 1265
Step 24: 1265 + 55 = 1320
Step 25: 1320 + 55 = 1375
Step 26: 1375 + 55 = 1430
Step 27: 1430 + 55 = 1485
Step 28: 1485 + 55 = 1540
Step 29: 1540 + 55 = 1595
Step 30: 1595 + 55 = 1650
Step 31: 1650 + 55 = 1705
Step 32: 1705 + 55 = 1760
Step 33: 1760 + 55 = 1815
Step 34: 1815 + 55 = 1870
Step 35: 1870 + 55 = 1925
Step 36: 1925 + 55 = 1980
Step 37: 1980 + 55 = 2035
Step 38: 2035 + 55 = 2090
Step 39: 2090 + 55 = 2145
Step 40: 2145 + 55 = 2200
Step 41: 2200 + 55 = 2255
Step 42: 2255 + 55 = 2310
Step 43: 2310 + 55 = 2365
Step 44: 2365 + 55 = 2420
Step 45: 2420 + 55 = 2475
Step 46: 2475 + 55 = 2530
Step 47: 2530 + 55 = 2585
Step 48: 2585 + 55 = 2640
Step 49: 2640 + 55 = 2695
Step 50: 2695 + 55 = 2750
Step 51: 2750 + 55 = 2805

So, 55*51 = 2805
