Without delay, let's solve this. We've got 667 and we will be multiplying it by 9, that is, adding 667 to itself 9 times.
Step 1: 0 + 667 = 667
Step 2: 667 + 667 = 1334
Step 3: 1334 + 667 = 2001
Step 4: 2001 + 667 = 2668
Step 5: 2668 + 667 = 3335
Step 6: 3335 + 667 = 4002
Step 7: 4002 + 667 = 4669
Step 8: 4669 + 667 = 5336
Step 9: 5336 + 667 = 6003

So, 667*9 = 6003
