points$)$ Given the following expression:

a$-$b$*$c$/$d$+$e$*$f$-$g$/$h$.$

a$.$ Using the rules of precedence write this expression with parentheses and$/$or square bracket; show the

order of evaluation of the infix expression, by

first evaluating $*$ and $/$ from left to right, and

then evaluating $+$ and $-$ from left to right.

Create the binary infix tree for this expression $($WITHOUT parentheses or square brackets$).$

c$.$ Show the prelix expression corresponding to the infix trec.

d$.$ Show the postfix expression corresponding to the infix trec.

Then let a $=-2.$ b$=-1,$ c$=0,$d$=1,$c$=2,$ f$=3,$ g $=4,$ and h $=2,$ and using these values:

Show each step in the order of evaluation for a$),$ above

$11.$

Show each step in the order of evaluation for c$),$ above

Show each step in the order of evaluation for d$).$ above
