Sure thing! We've got 942 and we're gonna multiply it by 19. That's the same as adding 942 to itself 19 times.
Step 1: 0 + 942 = 942
Step 2: 942 + 942 = 1884
Step 3: 1884 + 942 = 2826
Step 4: 2826 + 942 = 3768
Step 5: 3768 + 942 = 4710
Step 6: 4710 + 942 = 5652
Step 7: 5652 + 942 = 6594
Step 8: 6594 + 942 = 7536
Step 9: 7536 + 942 = 8478
Step 10: 8478 + 942 = 9420
Step 11: 9420 + 942 = 10362
Step 12: 10362 + 942 = 11304
Step 13: 11304 + 942 = 12246
Step 14: 12246 + 942 = 13188
Step 15: 13188 + 942 = 14130
Step 16: 14130 + 942 = 15072
Step 17: 15072 + 942 = 16014
Step 18: 16014 + 942 = 16956
Step 19: 16956 + 942 = 17898

So, 942*19 = 17898
