Without delay, let's solve this. We've got 608 and we will be multiplying it by 7, that is, adding 608 to itself 7 times.
Step 1: 0 + 608 = 608
Step 2: 608 + 608 = 1216
Step 3: 1216 + 608 = 1824
Step 4: 1824 + 608 = 2432
Step 5: 2432 + 608 = 3040
Step 6: 3040 + 608 = 3648
Step 7: 3648 + 608 = 4256

So, 608*7 = 4256
