Question about Casio Office Equipment & Supplies

# Desk-top calculator operation

I know this might sound stupid but I can't work out how to add and/or subtract on this model and can't understand the pictorial instrucions in the manual.

I can get the = sign to calculate division and multiplication but when I want to simply add columns of figures and then subtract I don't know how to do so. I only bought the machine this week and already it's driving me nuts.

Any advice you can give me would be gratefully received. Thanks

Thanks very much for having the courtesy and taking the time to reply I'm really grateful. Believe it or not, my problem is even simpler than this. If I want to add a list of financial items to show outgoings and incomings e.g. £15,000 + £11,500 + £26,000 - an outgoing of £10,000 I can't even perform this simple operation. If I add the 15,11.5 and 26 and press = nothing happens. If I press the + sign once more it adds the three numbers. If however I want to then deduct the 10 and press= still nothing happens and I don't know how to get it to display the £37,500 I'm looking for.

when two negative numbers subtract they should add together. but this calculator is subtracting. -39--11 should be -50 but it said -28. Why?

First keep the manual aside .
From "columns of figures ",do u mean a set of calculations.If this is the case, if your calculator has brackets{ } or [ ] ,use this function to add or subtract columns of figures.
Eg: [789+546+123+852+6547+65]=8922
OR
[789+587+6598+458] - [ 548+2587+456+584]=
8432 - 4175 = 4257
I hope this solution solves your problem.
