I was doing pretty good but this one has me baffled. (56-((2x(9/(21-18)))+4))-40 I have tried several ways no luck. Thanks for any help.

do it in steps. inside out. i also kept the parenthesis in longer then necessary to show a point.
(56-((2x(9/(21-18)))+4))-40
(56-((2x(9/(3)))+4))-40
(56-((2x(9/3))+4))-40
(56-((2x(3))+4))-40
(56-((2x3)+4))-40
(56-((6)+4))-40
(56-(6+4))-40
(56-(10))-40
(56-10)-40
(46)-40
46-40

and if you paste
(56-((2*(9/(21-18)))+4))-40=
into windows calculator or google you will get an answer.
NOTE, use * for 'multiply' in arithmetic because if you use x it thinks you are doing algebra and x is a variable so it plots something
and i put the = sign there as calculator will not complete an entry without it
