EastWind [94]

Answer:

11

Step-by-step explanation:

  1. 9+3(8-3(7-5))-4
  2. 9+3(8-3(2))-4
  3. 9+3(8-6)-4
  4. 9+3(2)-4
  5. 9+6-4
  6. 15-4
  7. 11

I first delt with simplifying the parentheses till step five. Then in five I just added 9+6 because it came before the -4. But PEMDAS is very important when doing these problems because it tell you the order

  • P (parentheses)
  • E (exponents)
  • M (multiply)
  • D (divide)
  • A (add)
  • S (subtract)
  • **the biggest thing is that with multipe and divide it depends what comes first. If you see divide before multipe in the problem just do it that way. It is the same way with add and subtract but The multiple/divide group ALWAYS comes BEFORE add/subtract
