I made and published this over a month ago and it turned out better than I had originally hoped but unfortuantely didn't gain as much popularity as I had hoped. I know that it's a little late to be making a thread for it, but i don't care. I'm hoping to get some opinions about the way it is now, get it some puplicity, and, above all, get some realistic ideas on how I can improve it. It may already use every wifi channel but that doesn't mean that it can't be improved (I could actually free up 7 channels just by making the add/subconverter convert enough numbers to not need a separate one for multiplication). I would definitlely appreciate it if someone could tell me a better way of doing multiplication (my method kinda sucks) since I know that there are better ones.
Some of the current features of the calculator are:
* double digits for add/sub
* multiplication and squaring numbers (single digits)

* can do limited multi operations
*add any amount of numbers together Ex. 5+9+15+20+1=50
*add/sub the result of add/sub calculations Ex. see description for an example
*if I expand the converter it will be able to add/sub the result of any calculation. Ex. 5^2=25+37=62
*multi operations with subtraction if only the last number is subtracted Ex. 13+7+35-23=32 but 13-7+20 will probably give you 40 as an answer

*checks for errors like triple digit numbers, double digits with multiplication/square,etc.
*checks for over/underflow
*a ready button so you always know when it's safe to hit the next button
*the adder/subtracter is the smallest that I've seen on tpt especially since it's 8-bit (I may be wrong about that one though)
*no hidden components. Everything is visible so you can watch it calculate

thanks and I knew about portal but it always got a little buggy when I tried to use it

seriously, that's y i never use it no matter what. If I run out of wifi, I try to use some creativity to free some up
