Let's roll up our sleeves and solve this. We have 86 and we're going to multiply it by 14, essentially adding 86 to itself 14 times.
Step 1: 0 + 86 = 86
Step 2: 86 + 86 = 172
Step 3: 172 + 86 = 258
Step 4: 258 + 86 = 344
Step 5: 344 + 86 = 430
Step 6: 430 + 86 = 516
Step 7: 516 + 86 = 602
Step 8: 602 + 86 = 688
Step 9: 688 + 86 = 774
Step 10: 774 + 86 = 860
Step 11: 860 + 86 = 946
Step 12: 946 + 86 = 1032
Step 13: 1032 + 86 = 1118
Step 14: 1118 + 86 = 1204

So, 86*14 = 1204
