# Arithmetic

This plugin allows you to evaluate arithmetic expressions in a zim page.

**Dependencies:** This plugin has no additional dependencies.

**See also:** the Inline Calculator plugin which does something similar

## Tutorial

You may do standard arithmetic operations in a document,

ending the operation with an equals sign, for example:

Single spaces may be used between the quantities and the

operators for clarity. Two or more spaces, or a colon

delimit an operation, like here: 100 + 1 =

You may use 'x' as the multiplication symbol in most

cases, or '*' if you want.

Operations can be... (2+7)x5 = anywhere!

Press <F5> now to obtain the results of all calculations

in the document. If you go up and modify some number,

press <F5> to recalculate.

You may do standard arithmetic operations in a document,

for example, assign values to two variables:

And define a formula: area = height x width

To obtain the result of the formula, press <F5>:

<F5> also updates the result of the area below,

after one of the values is modified: height = 25

Other examples of formulas, try modifying the values of f

and c will change after updating with <F5>:

c = (f - 32) x 5 / 9

f = 212 c =

f = 100 c =

f = 70 c =

f = 32 c =

f = -40 c =
