have an x button to help solve p
The x button would help solve the equation/problem
i.e (x+6)squared or 4(2x + 3) +5(x4)
I know there's a way of doing this on a sheet of paper, but for people to check their answers, i think it would be very useful!4 votes

Can you provide any more details?

A simple % calculation of 10% of 100 is 10.00 this app gives me a total different number
10% of 100.00 is 10, this app shows a total different number, pretty wild.

Scrolling is broken in conversion selection
I cannot scroll the conversion type selection. I can select Pressure by clicking the top of the box, which is barely visible, but I cannot select anything below it or read the word Pressure.

Add DMS converter
Put a button which converts a decimal e.g. 1.5 to DMS 1'30"
3 votesDegreeMinuteSecond converter like here
https://www.dcode.fr/convertangleunit 
Standard normal distribution table, Theta(z)=1/sqrt(2*pi) INTe^t²/2dt (over inifity to z) = P(Z<=z), Z~N(0,1);
Usage: Just type in a value for z (negative or positive) and press the Standard normal distribution table button.
Should also work backwards (then you put in the probability (0<p<1) and get the z instead) using ShiftButton or corresponding.
z values are between ~3.2 (p=0 for z<3.2) and 0,000 (p=0.5) and ~3.2 (p=1 for z>3.2)

Less eager selection extension in the converter view
When selecting a number value in the converter view, the selection range is automatically extended to include the unit designator, which makes copy/pasting the value into the calculator view more difficult than it needs to be.
I suggest not autoextending the selection, allowing the user to only select the numerical portion of the result.

look into this:i calculated the complex number i^2,your answer was too long,why the extra term
i^2=1 + 1.224646798818428e16i the answer suppose to be 1
so why the extra term?3 votes 
Abbreviate some of the longer unit names
Unit names, like Angstrom, are long and are likely to be accompanied by a long number, especially if not using scientific notation, since the unit size is so small. Converting even a small number like 1 cm to Angstroms results in a large number that is truncated. League is another kind of long name. Not sure what the abbreviation is for that.
