Modulus Calculator

Great - But! (Using & for the x^y key and setting mod to 37; = for the equals key, and -> for the displayed result) : 10&20 x 7 = -> 34 10&20 = -> 26, ac 26x7 = -> 34 10&20 = x 7 = -> 33 !!! Why does touching the = key to see an intermediate result cause it to produce a wrong answer. It does this for all ax^b I’ve tried with all mod values. Is there a reason? Otherwise a really great app!

It's really basic, such that you would probably only find it useful with another calculator if that calculator doesn’t have a modulus tool (or at least doesn’t have a modulus tool that saves the value that you're modulating by; requiring you to type the value in every single time...). Even then though, you probably would prefer to have a tool that would continuously run an equation with progressively changing variables. In my case, I was hoping to better visualize some equations to chew on the implications of the modulus tool, to develop a deeper intuition of cryptography with key signatures, but this is not an ideal tool for that either. The issue there is that every time you hit "=", the result of any modifications is automatically put through the modulus. An example: Let's say that we're trying to test the difficulty of finding a multiplicative-inverse (g^-1) of a combination of 'g' (publicly shared factor) and 'n' (the value to modulate by). You would first multiply g by some positive integer that acts as a secret key, or maybe a public key if you don't want to know the secret key first. if it's a large number, you may want to know the product first, but upon hitting the '=' you will only see the modulus output of the product, meaning you either need to have an exceedingly efficient mental multiplication ability, or use another calculator in combination with this one. Because of this, this app is most likely to be impractical for anyone to use, unless there is an update, which is probably not gonna happen as the dev. seems to no longer be maintaining this app.
