Without delay, let's solve this. We've got 619 and we will be multiplying it by 7, that is, adding 619 to itself 7 times.
Step 1: 0 + 619 = 619
Step 2: 619 + 619 = 1238
Step 3: 1238 + 619 = 1857
Step 4: 1857 + 619 = 2476
Step 5: 2476 + 619 = 3095
Step 6: 3095 + 619 = 3714
Step 7: 3714 + 619 = 4333

So, 619*7 = 4333
