Step 18: 15946 + 938 = 16884
Step 19: 16884 + 938 = 17822
Step 20: 17822 + 938 = 18760
Step 21: 18760 + 938 = 19698
Step 22: 19698 + 938 = 20636
Step 23: 20636 + 938 = 21574
Step 24: 21574 + 938 = 22512
Step 25: 22512 + 938 = 23450
Step 26: 23450 + 938 = 24388
Step 27: 24388 + 938 = 25326
Step 28: 25326 + 938 = 26264
Step 29: 26264 + 938 = 27202
Step 30: 27202 + 938 = 28140
Step 31: 28140 + 938 = 29078
Step 32: 29078 + 938 = 30016
Step 33: 30016 + 938 = 30954
Step 34: 30954 + 938 = 31892
Step 35: 31892 + 938 = 32830
Step 36: 32830 + 938 = 33768
Step 37: 33768 + 938 = 34706
Step 38: 34706 + 938 = 35644
Step 39: 35644 + 938 = 36582
Step 40: 36582 + 938 = 37520
Step 41: 37520 + 938 = 38458
Step 42: 38458 + 938 = 39396
Step 43: 39396 + 938 = 40334
Step 44: 40334 + 938 = 41272
Step 45: 41272 + 938 = 42210
Step 46: 42210 + 938 = 43148

So, 938*46 = 43148
