I am working on a cart page and would like to add two values: the # of products (static) + the state quantity (+ or - 1 depending on onClick). For example, I am getting a result like this "20+1" and when I click (+) it will become "20+2". How would I get the result to read just 22?

My code is this. props.ProductData.price is static and stata.quantity is increasing by 1 or -1:

```
<span className="quantity">{props.productData.price}+{state.quantity}</span>

```

Would I have to write a function? If so, could you help set it up? Thank you
