Hi,                                                      

 I am going to talk about PEMDAS. PEMDAS is a mathematical order in witch you preform math operations. For example, the order you preform when you have a question like 9² +(18+2)-(12+876).
PEMDAS means P-parenthies, E-exponents, M-multiplcation, D-divition, A-addition,and S-subtraction. PEMDAS is to be done in that order.That is why it is called order of operations.Always go left to right when doing it.


                                                          answer                                                                                                                                    


lets say we want to solve 9²(18-16)÷(11+1). So first we go in order of PEMDAS.So we start with parentasece in 9²(18-16)÷(11+1).18-16=2 and 11+1=12. Now the problem is 9²(2)÷(12).next is exponets.9x9=81. now it is 81(2)÷(12).Next we do multiplcation 81x2=162. Now the question is 162÷ 12 and now we do divtion. The answer is 13.5.If there was more you would do addition then subtraction.
