  Parentheses first then Division or Multiplication then add or subtract. PEDMAS

  8-5= 3 3*5=15 15+2=17

  Gotta distribute:

  2+(8+5)-(5+5)

  2+13-0

  15

    Still not how distribution works. That would be:

    2+((85)-(55))

    2+(40-25)

    2+(15)

    17

    Anything other than 17 is wrong. No matter how you go about your multiplication step.

    Wtf, no, if you distribute you get the same result:

    2 + 5(8 - 5) =

    2 + (5 × 8) + (5 × -5) =

    2 + (40) + (-25) =

    2 + 40  - 25 = 2 + 15 = 17

      Yes i am, but if you subtract 15 from both sides it’s 2.
