# multiply

Learn how to use the multiplication (*) operator in Notion formulas.

1

number * number

2

multiply(number, number)

The

`*`

operator follows the standard mathematical order of operations (PEMDAS). For more detail, see Operator Precedence.You can also use the function version,

`multiply()`

.1

12 * 4 // Output: 48

2

3

multiply(12,-4) // Output: -48

Since

**multiply**is a binary operator, it can only work on two*operands -*the objects which are being operated on (if - the*ternary operator -*is the only operator that works on three operands).If you need to work with more than two operands, the shorthand

`*`

is by far the easiest way to do it.1

4 * 5 * 5 // Output: 100

2

3

multiply(multiply(4,5),5) // Output: 100

Yes! Remember that the commutative property of multiplication states that the factors in a multiplication problem can be switched around without changing the final product.

The example database below shows the interest owned by three pirates who smartly invest some of their savings.

The

**Interest Earnings**formula shows the total amount of interest that their investment generates over a number of years, given a specific interest rate.This example uses the simple interest formula

$Prt$

, where:- $P$is the principal
- $r$is the rate of interest converted to a decimal (e.g. 7% is converted to 0.07)
- $t$is the number of period (in this case, years)

To get a final balance (principal + simple interest), you’d use the formula

$A=P(1+rt)$

.See that example at the Simple Interest Calculator database, or learn more with this Calculator Soup calculator.

Instead of using hard-coded numbers, I’ve called in each property using the

`prop()`

function. My name is Thomas Frank, and I'm a Notion-certified writer, YouTuber, and template creator.
