OK, let's work through this together. We're starting with 926 and we're going to multiply it by 19, which means we add 926 to itself 19 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

So, 926*19 = 17594
