Let's roll up our sleeves and solve this. We have 846 and we're going to multiply it by 14, essentially adding 846 to itself 14 times.
Step 1: 0 + 846 = 846
Step 2: 846 + 846 = 1692
Step 3: 1692 + 846 = 2538
Step 4: 2538 + 846 = 3384
Step 5: 3384 + 846 = 4230
Step 6: 4230 + 846 = 5076
Step 7: 5076 + 846 = 5922
Step 8: 5922 + 846 = 6768
Step 9: 6768 + 846 = 7614
Step 10: 7614 + 846 = 8460
Step 11: 8460 + 846 = 9306
Step 12: 9306 + 846 = 10152
Step 13: 10152 + 846 = 10998
Step 14: 10998 + 846 = 11844

So, 846*14 = 11844
