 ## Multiply Two Decimals with JavaScript
+JavaScript uses the `*` symbol for multiplication. Multiplying floats is the same as multiplying integers. JavaScript only has the *number* type, which serves both integer and floating point numbers, it does not have a specific type for integers.

+For example, if you were to multiply 2 integers, the numbers 3 and 5, then you could simply type:
+```javascript
+var product = 3 * 5; // product is 15
+``` 
+Now if we were to multiply two floating point numbers, 3.4 and 5.7, the product would be a float as well:
+```javascript
+var product = 3.4 * 5.7; // product is 19.38
+```
