# Typing Math

In this post I will try to explain some of the UX problems that I need to solve as soon as possible for my project.

## Description

In LaTeX the solution of quadratic equation is represented by

```
x = \frac{-b \pm \sqrt{b^2 - 4 a c}}{2 a}
```

and will be render as

$$x\; =\; \backslash frac\{-b\; \backslash pm\; \backslash sqrt\{b^2\; -\; 4\; a\; c\}\}\{2\; a\}$$Using Firefox OS native English keyboard to type LaTeX representation of the solution of quadratic equation the user need to type:

x | ?123 | ALT | = | \ | ABC | f | r | a | c | ?123 | ALT | { | ALT | – | ABC | b | ... |

You can check the keys with the screenshot below:

One of the goals of my project is reduce the number of switches between keyboard layers and also the number of key typed.

Having enabled the English keyboard and my currently prototype (available at GitHub) to type the same equation the user will need to type:

x | = | x/y | – | b | ... |

## UX Problem

So far I believe that I need to add five layouts to the standard ones:

- lowercase Greek letters
- uppercase Greek letters
- basic math operators
- math functions
- set operators

**How quickly switch between this keyboard layouts?** Use the globe with
meridians is suitable?
