Let's roll up our sleeves and solve this. We have 40 and we're going to multiply it by 14, essentially adding 40 to itself 14 times.
Step 1: 0 + 40 = 40
Step 2: 40 + 40 = 80
Step 3: 80 + 40 = 120
Step 4: 120 + 40 = 160
Step 5: 160 + 40 = 200
Step 6: 200 + 40 = 240
Step 7: 240 + 40 = 280
Step 8: 280 + 40 = 320
Step 9: 320 + 40 = 360
Step 10: 360 + 40 = 400
Step 11: 400 + 40 = 440
Step 12: 440 + 40 = 480
Step 13: 480 + 40 = 520
Step 14: 520 + 40 = 560

So, 40*14 = 560
