Considering the operator definition:

$[5*2$pts $=10$ pts$]$

name$($inputl type, input$2$ t y p e $,...)$ output$\_$type

$$ You are given the following operators:

$+($float$,$ float$)$ float $($addition$)$

$*$int$,$ int$)$ int $($multiplication$)$

$/($int$,$ int$)$ int $($integer division$)$

$>($int$,$ int$)$ boolean $($greater than$)$

$!($boolean$)$ boolean $($logical NOT$)$

$||($boolean$,$ boolean$)$ boolean $($logical OR$)$

$==($float$,$ float$)$ boolean $($equality for floats$)$

Note: Operator: $+($float$,$ float$)$ float, means it takes two floats, performs an add opera$-$

tion on them, and outputs a float.

Using the given operators, decide whether the following expressions $(($a$)$ to $($e$))$ are ty$-$

peable or not. If the expression is typeable $($able to be reduced to a typed expression$),$ give

its type and expected output. Otherwise, give an explanation of why it is not typeable.

$1.!(5>3)$

$2.100/$ x; given x $=$ "twenty"

$3.45.0+19.0$

$4.45*(3>2)$

$5.99\mathrm{.}0==(50\mathrm{.}0+49\mathrm{.}0)$
