Sure thing, let's get straight to it. We start with 135 and we're going to multiply it by 50, which means adding 135 to itself 50 times.
Step 1: 0 + 135 = 135
Step 2: 135 + 135 = 270
Step 3: 270 + 135 = 405
Step 4: 405 + 135 = 540
Step 5: 540 + 135 = 675
Step 6: 675 + 135 = 810
Step 7: 810 + 135 = 945
Step 8: 945 + 135 = 1080
Step 9: 1080 + 135 = 1215
Step 10: 1215 + 135 = 1350
Step 11: 1350 + 135 = 1485
Step 12: 1485 + 135 = 1620
Step 13: 1620 + 135 = 1755
Step 14: 1755 + 135 = 1890
Step 15: 1890 + 135 = 2025
Step 16: 2025 + 135 = 2160
Step 17: 2160 + 135 = 2295
Step 18: 2295 + 135 = 2430
Step 19: 2430 + 135 = 2565
Step 20: 2565 + 135 = 2700
Step 21: 2700 + 135 = 2835
Step 22: 2835 + 135 = 2970
Step 23: 2970 + 135 = 3105
Step 24: 3105 + 135 = 3240
Step 25: 3240 + 135 = 3375
Step 26: 3375 + 135 = 3510
Step 27: 3510 + 135 = 3645
Step 28: 3645 + 135 = 3780
Step 29: 3780 + 135 = 3915
Step 30: 3915 + 135 = 4050
Step 31: 4050 + 135 = 4185
Step 32: 4185 + 135 = 4320
Step 33: 4320 + 135 = 4455
Step 34: 4455 + 135 = 4590
Step 35: 4590 + 135 = 4725
Step 36: 4725 + 135 = 4860
Step 37: 4860 + 135 = 4995
Step 38: 4995 + 135 = 5130
Step 39: 5130 + 135 = 5265
Step 40: 5265 + 135 = 5400
Step 41: 5400 + 135 = 5535
Step 42: 5535 + 135 = 5670
Step 43: 5670 + 135 = 5805
Step 44: 5805 + 135 = 5940
Step 45: 5940 + 135 = 6075
Step 46: 6075 + 135 = 6210
Step 47: 6210 + 135 = 6345
Step 48: 6345 + 135 = 6480
Step 49: 6480 + 135 = 6615
Step 50: 6615 + 135 = 6750

So, 135*50 = 6750
