How do you evaluate #45\div [ ( 10- 2) \times 2- 11]#?
Use the order of operation to find the value of the expression
remember it this way "if you get hurt in (PE call an Medical Doctor, As Soon as possible)
PE is one class so do exponents and parenthesis at the same time.
MD is one person so do Multiplication and Division at one time working from left to right.
ASap is one time so do Addition and Subtraction together working from left to right
Start with the intermost parenthesis
Next do the multiplication with the parenthesis
Next do the subtraction within the parenthesis
Next do the final division problem
Work from the inner bracket outwards.
