Alright, let's solve this math problem step by step. First, we have the number 667. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 8. So, we're going to take the number 667 and add it to itself 8 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

So, 667*8 = 5336
