Answer 1

please help n one is helping me

Answer 2

step 3 to step 4. Gotta mulitply before ya add.

Answer 3

so its step 3?

Answer 4

I guess. Step 4 is where he has it wrong, so I would assume it counts as step 3 where the mistake is. Guess it depends on how technical it gets. Either way, you have to multiply before you add. Can you see where there was addition instead of multiplication?
