3.Multiplication.

4.Addition.

Explanation:

You have to follow the P.E.M.D.A.S., this is:

P:Parenthesis first.

E:Exponent next.

M:Multiplication.

D:Division.

(Multiplication and Division is whichever come first, from left to right)

(Addition and Subtraction is whichever come first, from left to right)

We have 2+(3-9)÷(-3)·4

First we have to do the subtraction (because it's between parenthesis):

2+(-6)÷(-3)·4

Second we have to do the division because it's on the left:

2+2·4

Third we have to do the multiplication:

`2+8`

Fourth we have to do the addition:

`10`
