Guys, isn’t multiplication done *before* division in JS? Because I was testing around with this code `10 / 2 * 10;`

, which the output will equal `50`

, so I decided to break it down to find out if multiplication is done before division and will the output be the same? First I multiplied `2 * 10;`

and I got `20`

, then I divided by the other `10`

, like this `10 / 20`

, and I got `.5`

, or `2`

, if it’s done the other way around, but none of them equal to `50`

, as it suppose to be. So then I decided to test with dividing first. So here is our code again `10 / 2 * 10;`

, so I first did `10 / 2;`

, which got me `5`

, then I multiplied it `5 * 10;`

, and got `50`

, the same output as typing the whole thing in. So unless I’m making a mistake here, division goes before multiplication not the other way around, right?

Hello!

Mathematically, I believe you are looking at this incorrectly when you try to do the multiplication first.

`10/2*10`

is the same as `10*10/2`

. But performing the `2*10`

first changes your initial statement to `10/(2*10)`

.

Multiplication and Division have the same precedence in JavaScritpt. When left associative operators (most operators) have the same precedence they are executed left to right.

Take a look a the “Table” that lists precedence here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Operator_Precedence

So the multiplication is done first, but I just didn’t break it down correctly?

So you’re saying both multiplication and division have the same priority, so multiplication = division, and it just depends where on the line they are?

Yup, unless you use a higher precedence operator like () to change this.

Yeah, that’s an abridged list. The full list is at the MDN link I provided.
