OK, let's work through this together. We're starting with 187 and we're going to multiply it by 48, which means we add 187 to itself 48 times.
Step 1: 0 + 187 = 187
Step 2: 187 + 187 = 374
Step 3: 374 + 187 = 561
Step 4: 561 + 187 = 748
Step 5: 748 + 187 = 935
Step 6: 935 + 187 = 1122
Step 7: 1122 + 187 = 1309
Step 8: 1309 + 187 = 1496
Step 9: 1496 + 187 = 1683
Step 10: 1683 + 187 = 1870
Step 11: 1870 + 187 = 2057
Step 12: 2057 + 187 = 2244
Step 13: 2244 + 187 = 2431
Step 14: 2431 + 187 = 2618
Step 15: 2618 + 187 = 2805
Step 16: 2805 + 187 = 2992
Step 17: 2992 + 187 = 3179
Step 18: 3179 + 187 = 3366
Step 19: 3366 + 187 = 3553
Step 20: 3553 + 187 = 3740
Step 21: 3740 + 187 = 3927
Step 22: 3927 + 187 = 4114
Step 23: 4114 + 187 = 4301
Step 24: 4301 + 187 = 4488
Step 25: 4488 + 187 = 4675
Step 26: 4675 + 187 = 4862
Step 27: 4862 + 187 = 5049
Step 28: 5049 + 187 = 5236
Step 29: 5236 + 187 = 5423
Step 30: 5423 + 187 = 5610
Step 31: 5610 + 187 = 5797
Step 32: 5797 + 187 = 5984
Step 33: 5984 + 187 = 6171
Step 34: 6171 + 187 = 6358
Step 35: 6358 + 187 = 6545
Step 36: 6545 + 187 = 6732
Step 37: 6732 + 187 = 6919
Step 38: 6919 + 187 = 7106
Step 39: 7106 + 187 = 7293
Step 40: 7293 + 187 = 7480
Step 41: 7480 + 187 = 7667
Step 42: 7667 + 187 = 7854
Step 43: 7854 + 187 = 8041
Step 44: 8041 + 187 = 8228
Step 45: 8228 + 187 = 8415
Step 46: 8415 + 187 = 8602
Step 47: 8602 + 187 = 8789
Step 48: 8789 + 187 = 8976

So, 187*48 = 8976
