Let's get this math done. We have 162 and we're going to multiply it by 41. This is the same as taking 162 and adding it to itself 41 times.
Step 1: 0 + 162 = 162
Step 2: 162 + 162 = 324
Step 3: 324 + 162 = 486
Step 4: 486 + 162 = 648
Step 5: 648 + 162 = 810
Step 6: 810 + 162 = 972
Step 7: 972 + 162 = 1134
Step 8: 1134 + 162 = 1296
Step 9: 1296 + 162 = 1458
Step 10: 1458 + 162 = 1620
Step 11: 1620 + 162 = 1782
Step 12: 1782 + 162 = 1944
Step 13: 1944 + 162 = 2106
Step 14: 2106 + 162 = 2268
Step 15: 2268 + 162 = 2430
Step 16: 2430 + 162 = 2592
Step 17: 2592 + 162 = 2754
Step 18: 2754 + 162 = 2916
Step 19: 2916 + 162 = 3078
Step 20: 3078 + 162 = 3240
Step 21: 3240 + 162 = 3402
Step 22: 3402 + 162 = 3564
Step 23: 3564 + 162 = 3726
Step 24: 3726 + 162 = 3888
Step 25: 3888 + 162 = 4050
Step 26: 4050 + 162 = 4212
Step 27: 4212 + 162 = 4374
Step 28: 4374 + 162 = 4536
Step 29: 4536 + 162 = 4698
Step 30: 4698 + 162 = 4860
Step 31: 4860 + 162 = 5022
Step 32: 5022 + 162 = 5184
Step 33: 5184 + 162 = 5346
Step 34: 5346 + 162 = 5508
Step 35: 5508 + 162 = 5670
Step 36: 5670 + 162 = 5832
Step 37: 5832 + 162 = 5994
Step 38: 5994 + 162 = 6156
Step 39: 6156 + 162 = 6318
Step 40: 6318 + 162 = 6480
Step 41: 6480 + 162 = 6642

So, 162*41 = 6642
