OK, let's work through this together. We're starting with 926 and we're going to multiply it by 39, which means we add 926 to itself 39 times.
Step 1: 0 + 926 = 926
Step 2: 926 + 926 = 1852
Step 3: 1852 + 926 = 2778
Step 4: 2778 + 926 = 3704
Step 5: 3704 + 926 = 4630
Step 6: 4630 + 926 = 5556
Step 7: 5556 + 926 = 6482
Step 8: 6482 + 926 = 7408
Step 9: 7408 + 926 = 8334
Step 10: 8334 + 926 = 9260
Step 11: 9260 + 926 = 10186
Step 12: 10186 + 926 = 11112
Step 13: 11112 + 926 = 12038
Step 14: 12038 + 926 = 12964
Step 15: 12964 + 926 = 13890
Step 16: 13890 + 926 = 14816
Step 17: 14816 + 926 = 15742
Step 18: 15742 + 926 = 16668
Step 19: 16668 + 926 = 17594
Step 20: 17594 + 926 = 18520
Step 21: 18520 + 926 = 19446
Step 22: 19446 + 926 = 20372
Step 23: 20372 + 926 = 21298
Step 24: 21298 + 926 = 22224
Step 25: 22224 + 926 = 23150
Step 26: 23150 + 926 = 24076
Step 27: 24076 + 926 = 25002
Step 28: 25002 + 926 = 25928
Step 29: 25928 + 926 = 26854
Step 30: 26854 + 926 = 27780
Step 31: 27780 + 926 = 28706
Step 32: 28706 + 926 = 29632
Step 33: 29632 + 926 = 30558
Step 34: 30558 + 926 = 31484
Step 35: 31484 + 926 = 32410
Step 36: 32410 + 926 = 33336
Step 37: 33336 + 926 = 34262
Step 38: 34262 + 926 = 35188
Step 39: 35188 + 926 = 36114

So, 926*39 = 36114
