OK, let's work through this together. We're starting with 61 and we're going to multiply it by 48, which means we add 61 to itself 48 times.
Step 1: 0 + 61 = 61
Step 2: 61 + 61 = 122
Step 3: 122 + 61 = 183
Step 4: 183 + 61 = 244
Step 5: 244 + 61 = 305
Step 6: 305 + 61 = 366
Step 7: 366 + 61 = 427
Step 8: 427 + 61 = 488
Step 9: 488 + 61 = 549
Step 10: 549 + 61 = 610
Step 11: 610 + 61 = 671
Step 12: 671 + 61 = 732
Step 13: 732 + 61 = 793
Step 14: 793 + 61 = 854
Step 15: 854 + 61 = 915
Step 16: 915 + 61 = 976
Step 17: 976 + 61 = 1037
Step 18: 1037 + 61 = 1098
Step 19: 1098 + 61 = 1159
Step 20: 1159 + 61 = 1220
Step 21: 1220 + 61 = 1281
Step 22: 1281 + 61 = 1342
Step 23: 1342 + 61 = 1403
Step 24: 1403 + 61 = 1464
Step 25: 1464 + 61 = 1525
Step 26: 1525 + 61 = 1586
Step 27: 1586 + 61 = 1647
Step 28: 1647 + 61 = 1708
Step 29: 1708 + 61 = 1769
Step 30: 1769 + 61 = 1830
Step 31: 1830 + 61 = 1891
Step 32: 1891 + 61 = 1952
Step 33: 1952 + 61 = 2013
Step 34: 2013 + 61 = 2074
Step 35: 2074 + 61 = 2135
Step 36: 2135 + 61 = 2196
Step 37: 2196 + 61 = 2257
Step 38: 2257 + 61 = 2318
Step 39: 2318 + 61 = 2379
Step 40: 2379 + 61 = 2440
Step 41: 2440 + 61 = 2501
Step 42: 2501 + 61 = 2562
Step 43: 2562 + 61 = 2623
Step 44: 2623 + 61 = 2684
Step 45: 2684 + 61 = 2745
Step 46: 2745 + 61 = 2806
Step 47: 2806 + 61 = 2867
Step 48: 2867 + 61 = 2928

So, 61*48 = 2928
