###### The Formula Applet

- lets you create math or physics exercises as a H5P content type.
- You can provide an expression as solution, and Formula Applet checks if your solution is right or wrong.
- Algebraic equivalent solutions are also accepted.
- Formula Applet is able to deal with physical units.
- Formula Applet is open source.
- Formula Applet is written in JavaScript. These open source libraries are used: MathQuill, jQuery and Hammer.

- Check solution:
- Try again:
- The solutions are given in each case, so you can try them quickly. Solutions can be copied with
**copy and paste**(not on smartphones). - Formula Applet is not yet published at the H5P Hub

###### Physics Example

A voltage of

U=24\ \unit{V}

is applied to a resistor ofR=0,30\ \unit{M\Omega}

.What is the current I that flows through the resistor?

Solution:

80\unit{µA} = 0.080\unit{mA} = 8.0\cdot10^{-5}\unit{A}
