# Arithmetic functions maths

Arithmetic functions are used to perform basic calculations on values.

The `+` (addition) function is used to find the sum of two argument expressions.

Syntax

``````{%= double + double %}
``````

Example

The following operation sums the price of two different products.

``````{%= product1.price + product2.price %}
``````

## Multiply multiply

The `*` (multiplication) function is used to find the product of two argument expressions.

Syntax

``````{%= double * double %}
``````

Example

The following operation finds the product of the inventory and the price of a product to find the gross value of the product.

``````{%= product.inventory * product.price %}
``````

## Subtract substract

The `-` (subtraction) function is used to find the difference of two argument expressions.

Syntax

``````{%= double - double %}
``````

Example

The following operation finds the difference in price between two different products.

``````{%= product1.price - product2.price %}
``````

## Divide divide

The `/` (division) function is used to find the quotient of two argument expressions.

Syntax

``````{%= double / double %}
``````

Example

The following operation finds the quotient between the total products sold and total money earned to see the average cost per item.

``````{%= totalProduct.price / totalProduct.sold %}
``````

## Remainder remainder

The `%` (modulo/remainder) function is used to find the remainder after dividing the two argument expressions.

Syntax

``````{%= double % double %}
``````

Example

The following operation checks if the personâ€™s age is divisible by five.

``````{%= person.age % 5 = 0 %}
``````
