13

@L.T. can you help me

OpenStudy (anonymous):

@abrandon can you explain?!

OpenStudy (anonymous):

First of all, you do all operations from left to right Second, you need to start with multiplication and division, doing these from right to left\[4+5-(7*-2)\div2-3\]So multiply 7 by negative 2 and then divide by 2

OpenStudy (anonymous):

Then you can start (moving left to right) with addition and subtraction
