Let's roll up our sleeves and solve this. We have 43 and we're going to multiply it by 14, essentially adding 43 to itself 14 times.
Step 1: 0 + 43 = 43
Step 2: 43 + 43 = 86
Step 3: 86 + 43 = 129
Step 4: 129 + 43 = 172
Step 5: 172 + 43 = 215
Step 6: 215 + 43 = 258
Step 7: 258 + 43 = 301
Step 8: 301 + 43 = 344
Step 9: 344 + 43 = 387
Step 10: 387 + 43 = 430
Step 11: 430 + 43 = 473
Step 12: 473 + 43 = 516
Step 13: 516 + 43 = 559
Step 14: 559 + 43 = 602

So, 43*14 = 602
