Without delay, let's solve this. We've got 200 and we will be multiplying it by 7, that is, adding 200 to itself 7 times.
Step 1: 0 + 200 = 200
Step 2: 200 + 200 = 400
Step 3: 400 + 200 = 600
Step 4: 600 + 200 = 800
Step 5: 800 + 200 = 1000
Step 6: 1000 + 200 = 1200
Step 7: 1200 + 200 = 1400

So, 200*7 = 1400
