### calculator issue

I've been working with Scott's calculator, following this great tutorial  but I got an issue , well for me.

You press N1 + N2 = N3 and works great. But if you try something like  this :   N1+N2+N3 = calculator just remember last 2 numbers so in this case I just get  the result of N2+N3 .  So calculator it's not working with more than 2 operands (the last 2) . So it's necessary you click equals after 2 operands. SO how can I fix this? I've thinking and trying but nothing seems to work. Any help would be extremely appreciated :)

With the Math Blocks basic operands,display with    block + block    or block - block  or block x block.    By left clicking the blue box on the control, you can change that to allow:   block + block + block   or block x block x block x block x block       Knowing that might help.

You may have to save the result of the first to calculations, then do the second.    For instance, consider putting the result of N1+N2 into a global called TemporaryStorage.  Initialize TemporaryStorage to zero at the beginning of a calculation session.    so any the result  of N1+N2 = N1+N2+temporaryStorage  ; now temporaryStorage has the result of N1+N2   so, when you do  +N3, you might get    temporaryStorage + N3.

This is just a idea of how your logic might go.  Try some things.  When you arrive at a solution, come back and tell us what works.

Perhaps will read the post and have some ideas too?

Hey Steve,
Thank you for your help, you gave me some ideas (the temporary result).. I guess I fixed this I added a new procedure

I add this procedure to each operator button :D and it's working.  Thank you a lot. So now I'm able to get the result of adding any numbers when I press equals . So I can N1+N2+N3 -N4-N5=N6 or whatever jeje Remember please to check Scott's tutorial to fully understand this procedure  :D

Yes, Eduardo I had to figure out how to work around that.
So to do 3 + 4 + 6 you would do it this way:
3 + 4 =   (7 displays) + 6 =   (13 displays) etc.

Hey Scott, that worked very well. I replace "," with "." and fixed the problem, So I took a pic if anyone want to see the blocks to use them :D, thank you very much Scott!
