Combinatorics Mathematics

Very good app. Please include a highlight option to copy and paste so it can be directly transfered to ms word. Also, symbols like +, -, *,/ , e.t.c, to get should be able to be inputed to know how many places a sign can be in a combination. E.g A+B-C and A-B+C and so on. Also, numbers like 10 and above are splited as 1 and 0. Lastly, once the letters exceed z, signs should be inputed like π,£, e.t.c. I really love this app and appreciate your team!

5 stars because i want to support this app but please 🥺 add a search 🔍 feature that will highlight whatever i search for exactly how it does on google chrome. Then i would buy pro. I feel this is essential when dealing with so many combinations or permutations and i just want to quickly get to the section that interests me. Thank you!

While i appreciate the effort, it does not show part permutations without repeats. Who cares that you can show the same letters in many repetitive ways? IE with "banana" you can show aa in 6 different ways! So what? And there's no choice. Please rectify to make it more interesting and useful. Anagrams show different combinations but only using all the letters. Why can't anybody get it right?

Very useful to learn and understand permutations or combinations. Would be really helpful to have much more information regarding the output and be able to use full Unicode symbols to have colorful icons in the output. For anyone interested, there is a free Windows program called Simple Solver that does this with a bit more features. Maybe it can be used on Android with a proot environment like UserLAnd, AnLinux or AndroNix - and Wine🍷Or a deeper Linux install if you have a rooted device.

Hi the app is great but the problem I can not do combination of numbers like 10,33 and so on. It counts them as two numbers. I wish it could also do such combinations

This app is exact what i need. There is complete concept that i need to implement. One thing that i missed that user can put only single alphabet not special charactor and multiple charactor.

This is very helpful app. It's gave me very helpfull tips for become Rich 💰

The application in Combination mode freezes at n = 38..k= 6..fix this please.....

Best app but it does not include all payment option and I can not use visa card to paid.

Easy to use, making understanding a difficult subject simple

Nice app really, but would be nicer if is supported calculations involving numbers eg: 23,56,56

if its possible to get pemutation numbers without repetition or export to xl is best....

So easy to use and very helpful to combined any digit number.thank you

It's good but give copy and paste facility also.

Can't copy combinations! Add copy feature to copy all combinations

Nice I have love to get this kind of apps since to enhance my idea in dealings. Thanks
