This is a subtraction problem.
Yeah, I know it is, but can you help me with the answer, please? What I did was I took 10 - 3.2 which equals 6.8 and then I multiplied 6.8 x 2 because n equals 2. 6.8 x 2 = 13.6. So I must be doing it wrong but I don't know-how.
You must multiply 3.2 by 2 first, then subtract that from 10. So 10-6.4=3.6.
Oh ok, that makes sense. Thank you so much!
