Średnia - Matematyka Icon in Material Style

This Średnia - Matematyka icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,300 icons, all in the same style and quality.
The icon looks very similar to a square that has been rotated 45 degrees in the shape of a diamond. The square was then split from the top corner to the bottom corner and the two pieces were pulled apart.
