What we did lately at math

We did math language which are:  Brakets ( 543.66)
                                                    Exponents
                                                    Multiplication 4x90 Multipication and divison are the same.
                                                    Division
                                                    Addition 87+34 addition and subtraction are the same.
                                                    Subtraction 98-55
You have to put them in the right order when you do this because if not you will get the wrong answer and mess the whole thing up.
