Let's roll up our sleeves and solve this. We have 310 and we're going to multiply it by 14, essentially adding 310 to itself 14 times.
Step 1: 0 + 310 = 310
Step 2: 310 + 310 = 620
Step 3: 620 + 310 = 930
Step 4: 930 + 310 = 1240
Step 5: 1240 + 310 = 1550
Step 6: 1550 + 310 = 1860
Step 7: 1860 + 310 = 2170
Step 8: 2170 + 310 = 2480
Step 9: 2480 + 310 = 2790
Step 10: 2790 + 310 = 3100
Step 11: 3100 + 310 = 3410
Step 12: 3410 + 310 = 3720
Step 13: 3720 + 310 = 4030
Step 14: 4030 + 310 = 4340

So, 310*14 = 4340
