## SADMEP instead of PEMDAS

We write our expressions with the understanding that a reader will order the operations involved using PEMDAS, or as I like to write with my students P/E/MD/AS. This is a convention. On Mars though a very different convention is observed. They use SA/DM/E/P to parse their expression.
Question 1: How would a Martian evaluate the following expression?
$-4+6(2-5)^2$
We, of course, get 50 using PEMDAS, but what would the Martians get?

Question 2: How could we translate $-4+6(2-5)^2$ into Martian, so they end up doing the operations in same order as we do? How can we rewrite the expression so they evaluate it to 50? (Note: in my answer I took the Martian use of nested parentheses to be outside in, instead of inside out like ours–they’re Martians after all, and I couldn’t get it to work any other way )
