The solver supports horizontal, vertical and multiline calculations, one at a time, using the following symbols:

Basic Operations: %, +/-
Basic Operators: +, -, x, ÷
Basic Functions: |x|, 1/x, √, ln, log, e^x, x^y, x², x!
Brackets: ( )
Trigonometry: cos, sin, tan, acos, asin, atan
Constants: π, e, φ

Nebo does not support operations with multiple variables. However, it can be used to solve an equation with one variable. Use the '?' sign to name the unknown.

Besides, several options are available. Tap ... at the top right hand corner of the object to choose between a truncated or rounded result, an angle unit in degrees or radians and whether you want your equation to be automatically solved or not.

Nebo Math recognition is almost as powerful as our core technology! It can recognize (but won't solve) equations including the main mathematical symbols: latin alphabet, digits, operators, frequent Greek symbols, common mathematics terms and international convention units. 

Based on the latest core technology (sdk 8), Math objects of Nebo 1.3 offer multiline equations and matrices recognition. In that case, we recommend disabling the solver manually. It can be done in the app settings or in the Math block as shown above.
