Calculate mathematical equations in notes

In Microsoft Office OneNote 2007, you can write down various figures during a meeting, conference, or class, and OneNote can instantly calculate the results for you.

Perform a simple calculation in your notes

  1. On any page in your notes, place the cursor where you want the result of a calculation to appear.
  2. Type out the mathematical expression that you want OneNote to calculate. For example, type 47+120+768 to calculate the sum of the numbers 47, 120, and 768, or SQRT(3) to calculate the square root of 3.

 Notes 

  • Do not use spaces in the expression. Type the numbers, operators, and functions as one single, continuous string of text.
  • Function codes are not case-sensitive. For example, typing SQRT(3)= will yield the same answer as sqrt(3)= or Sqrt(3)=.
  1. Immediately after the expression, type an equals sign (=) and then press SPACEBAR. OneNote calculates and places the answer after the equals sign.

 Tip   To create a new line after the answer, press ENTER (instead of SPACEBAR) after the equals sign.

 Note   When the answer appears after the equals sign, you can delete the expression that precedes it. The answer will remain in place. This is useful when you want only the final figure to appear in your notes.

Examples of simple calculations

Below are a few examples of mathematical expressions that OneNote can calculate.

  • Type $670/12= and then press SPACEBAR to calculate the average monthly sales of a product that creates a total of $670,000 per year in revenue.
  • Type 14*$39.99= and then press SPACEBAR to calculate the cost of 14 loads of materials at $39.99 a load.
  • Type sin(30)= and then press SPACEBAR to calculate the sine of a 30-degree angle.
  • Type (6+7) / (4*sqrt(3))= and then press SPACEBAR to calculate the answer to this more complex mathematical equation — (6+7) divided by (4 times the square root of 3).
