Sometimes, we want to force JavaScript to do math instead of putting two strings together.

In this article, we’ll look at how to force JavaScript to do math instead of putting two strings together.

### How to force JavaScript to do math instead of putting two strings together?

To force JavaScript to do math instead of putting two strings together, we should make sure we’re using arithmetic operators with numbers.

For instance, we write

```
const x = +"11.5" + +"3.5";
```

to convert `'11.5'`

and `'3.5'`

to numbers with the unary `+`

operator.

Then we add the returned numbers together and assign the sum to `x`

.
