Let's get this math done. We have 313 and we're going to multiply it by 6. This is the same as taking 313 and adding it to itself 6 times.
Step 1: 0 + 313 = 313
Step 2: 313 + 313 = 626
Step 3: 626 + 313 = 939
Step 4: 939 + 313 = 1252
Step 5: 1252 + 313 = 1565
Step 6: 1565 + 313 = 1878

So, 313*6 = 1878
