You don’t need a calculator to find the answers to simple math problems. You can jot down math equations during a meeting, conference or class, and OneNote can instantly calculate the results for you.

1. Type the equation you want to calculate. For example, type 95+83+416 to calculate the sum of the numbers 95, 83, and 416, or SQRT(15) to calculate the square root of 15.

2. After the equation, without typing a space, type an equal sign (=), and then press Spacebar. The answer will appear after the equal sign.

Tips:

• Don’t use spaces in the equation. Type the numbers, operators, and functions as one single, continuous string of text.

• Function codes are not case-sensitive. For example, SQRT(3)=, sqrt(3)= or Sqrt(3)= will calculate the same answer.

• To create a new line after the answer, press Enter (instead of Spacebar) after the equal sign.

If you want only the answer in your notes, after it’s calculated, you can delete the equation that precedes it. The answer will stay in your notes.

## Examples of simple calculations

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

• The average monthly sales of a product.    For example, if the total revenue per year is \$215,000, type \$215,000/12= and then press Spacebar.

• Total cost of monthly payments.    For example, type 48*\$129.99= and then press Spacebar to calculate the cost of 48 monthly payments at \$129.99 a payment.

• The sine of a 30-degree angle.    For example, type sin(30)= and then press Spacebar.

• More complete math equations.    For example, Type (6+7) / (4*sqrt(3))= and then press Spacebar to calculate the answer to (6+7) divided by (4 times the square root of 3).

## Supported arithmetic operators

You can use the following operators in your equations.

 Operator Meaning Example + (plus sign) Addition 3+3 - (minus sign) SubtractionNegation 3-1-1 * (asterisk) Multiplication 3*3 X (upper- or lowercase) Multiplication 3x3 / (forward slash) Division 3/3 % (percent sign) Percent 20% ^ (caret) Exponentiation 3^2 ! (exclamation) Factorial computation 5!

## Supported math and trigonometry functions

You can use the math and trigonometry functions in the following table for your equations.

Note:  To calculate a function, type its code (for example, SQRT for square root), and immediately follow it with the number, angle, or variables in parentheses, as shown in the Syntax column.

 Function Description Syntax ABS Returns the absolute value of a number ABS(number) ACOS Returns the arccosine of a number ACOS(number) ASIN Returns the arcsine of a number ASIN(number) ATAN Returns the arctangent of a number ATAN(number) COS Returns the cosine of a number COS(number) DEG Converts an angle (in radians) to degrees DEG(angle) LN Returns the natural logarithm of a number LN(number) LOG Returns the natural logarithm of a number LOG(number) LOG2 Returns the base-2 logarithm of a number LOG2(number) LOG10 Returns the base-10 logarithm of a number LOG10(number) MOD Returns the remainder of a division operation (number)MOD(number) PI Returns the value of π as a constant PI PHI Returns the value of Φ (the golden ratio) PHI PMT Calculates a loan payment based on a constant interest rate, a constant number of payments, and the present value of the total amount PMT(rate;nper;pv) RAD Converts an angle (in degrees) to radians RAD(angle) SIN Returns the sine of the given angle SIN(angle) SQRT Returns a positive square root SQRT(number) TAN Returns the tangent of a number TAN(number)
