Question 927062: My equation is -20/5-(-3)^2 The answer I got using the order of operation is 5 but the algebra calculator says -13. This answer requires me to divide before doing exponent. Why would I not use order of operation?

-20/5-(-3)^2 has the calculator thinking you mean

but what you really want is

-20/(5-(-3)^2)
