Without delay, let's solve this. We've got 424 and we will be multiplying it by 7, that is, adding 424 to itself 7 times.
Step 1: 0 + 424 = 424
Step 2: 424 + 424 = 848
Step 3: 848 + 424 = 1272
Step 4: 1272 + 424 = 1696
Step 5: 1696 + 424 = 2120
Step 6: 2120 + 424 = 2544
Step 7: 2544 + 424 = 2968

So, 424*7 = 2968
