Math Context Menu

✏️ Context menu — try it

Draw a circle around any math expression to open the context menu.

Compute

Write √16= or 5+3=, draw a circle around it → Compute numerical result

Function evaluation

Write f(x)=x², draw a circle → Evaluate function, set range −5 to 5

Set variable

Write 2x+5=, draw a circle → Set variable value, enter a number, then Compute

Check diagnostic

Write 1/0=, draw a circle → Check diagnostic to see why computation fails

Expression needs to be completed.

⚠ TOO_MANY_VARIABLES

Too many undefined variables to solve.

✗ DIVISION_BY_ZERO

Computation leads to division by zero.

✗ NUMBER_OVERFLOW

Result is too large to compute.

✗ INVALID_OPERATION

Invalid mathematical operation.

ℹ NO_VARIABLE / NOT_APPLICABLE
