+# --description--
+
+In JavaScript, you can also perform calculations with decimal numbers, just like whole numbers.
+
+Let's multiply two decimals together to get their product.
+
+# --instructions--
+
+Change the `0.0` so that product will equal `5.0`.
+
+# --hints--
+
+The variable `product` should equal `5.0`.
+
+```js
+assert(product === 5.0);
+```
+
+You should use the `*` operator
+
+```js
+assert(/\*/.test(__helpers.removeJSComments(code)));
+```
+
+# --seed--
+
+## --seed-contents--
+
+```js
+const product = 2.0 * 0.0;
+```
+
+# --solutions--
+
+```js
+const product = 2.0 * 2.5;
+```
