Nebo can recognize basic math in text blocks (e.g. 3 x 6), but to add equations to your notes or have Nebo perform calculations for you, you should create Math objects:

- Double-tap anywhere on your page or tap in the top right corner, then choose
**Math**. - Start writing your formula in the Math object.
- To convert your formula, double-tap anywhere in the Math object.

Only numbers and recognized symbols can be used in Math objects. If non-recognized symbols, lines and notations are used in the Math object, Nebo will attempt to interpret and incorporate them into the equation. This may cause the page to become slow or unstable.

## Supported operations and symbols (by the math solver)

Operations:

- Horizontal equations.
- Equations with one unknown, using '?'.
- Truncated or rounded results.
- Degrees or radiants for angle units.

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.

## Math object options

You can edit your Math object by mixing colors, changing object size, activating the solver, or moving the Math object anywhere else on your page.

### Mix colors

Before writing, go to the pen toolbar and tap the color of your choice. You can use as many colors as you need.

### Resize or move your Math object

Tap your Math object to select it. Then drag the handles around your object to resize it or use your finger to drag and drop your object anywhere you want.

### Convert your equations

To transform your handwritten equations into digital content, double-tap them. If the math solver is activated, your equation will be solved.

### Change approximation

Choose truncated or rounded numbers for the results of your calculations. To do so, tap your Math object to select it, then tap above the top right corner. Select **Truncated** or **Rounded** in the Math section.

### Change angle unit

Tap your Math object to select it, then tap above the top right corner. Select **Degree** or **Radiant**** **in the Math section.

### Deactivate the solver

Deactivating the solver will enable you to convert your handwritten equations into typeset without solving them. To do so, tap your Math object to select it, then tap above the top right corner, and disable **Calculation** in the Math section.

### General math settings

You can can set general settings to all your Math objects. To do so, go to **Settings** in the side panel. The settings you choose will be the default settings of all your Math objects.
