OK, let's crack this. We're given 614 and our task is to multiply it by 7. Essentially, we'll be adding 614 to itself 7 times.
Step 1: 0 + 614 = 614
Step 2: 614 + 614 = 1228
Step 3: 1228 + 614 = 1842
Step 4: 1842 + 614 = 2456
Step 5: 2456 + 614 = 3070
Step 6: 3070 + 614 = 3684
Step 7: 3684 + 614 = 4298

So, 614*7 = 4298
