here's my code

code:

var inum1,inum2 : real
var ch :char
get inum1
get inum2
get ch
if ch = '/' then
put inum1 / inum2
elsif ch = '*' then
put inum1 * inum2
elsif ch = '-' then
put inum1 - inum2
elsif ch = '+' then
put inum1 + inum2
end if

Just check to make sure that inum2 isn't equal to 0. If it's zero and they choose '/' then just don't do the operation. Try this in your if statement:

code:

if ch = '/' then
if inum2 not= 0 then
put inum1 / inum2
else
put "Can't divide by 0"
end if
%rest of if statement here
