## 20/20 Straight Line Equations Reviews in United States

### *---- "Not What I Expected"
It wasn’t an easy app to use. It had too many sections of subsections guides to follow, which were not clear to understand. Actually, it made algebra more difficult for me to understand. The creators must make this more user friendly for those who are trying to makes sense of algebra equations.
