Solve math equations with Math Assistant in OneNote

Applies To
OneNote for Microsoft 365 OneNote Math Assistant

Write or type any math problem and Math Assistant in OneNote can solve it for you—helping you reach the solution quickly, or displaying step-by-step instructions that help you learn how to reach the solution on your own. After solving your equation, there are many options to continue exploring math learning with Math Assistant.

Note

This feature is only available if you have a Microsoft 365 subscription for Enterprise or Education.

Step 1: Enter your equation

In the  Draw tab, write or type your equation. Use the  Lasso Select tool to draw a circle around the equation.

Problem Types Supported by Math Assistant

When you use Math Assistant in OneNote, you'll notice that the Select an action dropdown beneath the equation changes depending on your selected equation. Here are some of the problem types supported depending on the equation you're trying to solve.

Arrays For a list of real numbers, all of the below are supported.
  • Evaluate
  • Sort
  • Mean
  • Median
  • Mode
  • Sum
  • Product
  • Greatest Common Factor
  • Least Common Multiple
  • Variance
  • Standard Deviation
  • Minima
  • Maxima

    Array 5, 1, 3, 7 with the Math Assistant action menu

    For polynomials, the supported actions are Greatest Common Factor and Least Common Multiple. You can also choose to Graph in 2D to view the graphs of all your functions.

    Polynomial expressions with common-factor and graphing actions
Expressions For any expression, the available actions are:
  • Evaluate
  • Verify
  • Expand (if applicable)
  • Factor (if applicable)
  • Graph in 2D (only available if there is a variable)
  • Differentiate (only available if there is a variable)
  • Integrate (only available if there is a variable)

    Expression x squared minus 1 over x cubed minus 1 with Math Assistant actions
Equations and inequalities For equations and inequalities, the following actions are available:
  • Solve for {your variable}
  • Graph Both Sides in 2D — Each of the sides of the equality or inequality is graphed as a separate function.
  • Graph in 2D — A graph of the equation or inequality solutions
  • Graph Inequality — Marks the solution area on the graph

    Inequality 3x minus 2 less than or equal to 5 with solving and graphing actions
Systems It is important to have an equal number of equations and variables to ensure the correct functions are available. Systems can be written in two different ways:
  1. One below another, with or without a big brace before them

    System of two equations written vertically with a brace
  2. In one line divided by a comma

    System of two equations written on one line separated by a comma
Derivatives and integrals Derivatives can be written either with d/dx before the function, or with a prime mark.

Derivative of x times e to the x written in two equivalent forms

The actions available for derivatives and integrals are:
  • Evaluate
  • Graph in 2D
  • Differentiate
  • Integrate (for derivatives only)

    Integral of x squared with Math Assistant actions
Matrices Matrices can be written with square or round brackets. The following actions are supported for matrices:

  • Evaluate
  • Calculate Determinant
  • Invert Matrix
  • Calculate Trace
  • Transpose Matrix
  • Matrix Size
  • Reduce Matrix

Three by three matrix with matrix calculation actions

Matrix equations are not currently supported.
Graphing in polar coordinates To graph a function in polar coordinates, r needs to be expressed as a function of theta.
Polar equation r equals 1 plus cosine of 6 theta with its graph
Complex mode Note: Select Settings to switch between real numbers and complex numbers.

For complex expressions and numbers containing imaginary unit i, the following actions are available.
  • Evaluate
  • Real Part
  • Imaginary Part
  • Conjugate
  • Modulus
  • Argument
  • Differentiate (only if there is a variable)
  • Integrate (only if there is a variable)

    Complex expression 14 plus 7i minus 13 minus 6i with complex-number actions
