 **Dividing** numbers is done using the `/` operator. It works differently with **integers** and **floating point numbers**.
 
-* When we divide two integers, an **integer division** is applied and the obtained output is without its fractional part. Example: 11 / 3 = 3.
-* When we divide two numbers and at least one of them is a float number, a **floating division** is applied and the obtained result is a float number, just like in math. Example 11 / 4.0 = 2.75.  When it cannot be done with exact precision, the result is being rounded, for example 11.0 / 3 = 3.66666666666667.

 * The integer **division by 0** causes an **exception** during runtime \(runtime exception\).
 * Float numbers **divided by 0** do not cause an exception and the result is  **+/- infinity** or a special value  **NaN**. Example 5 / 0.0 = ∞.

-Did you notice **something strange**? Maybe you expected the numbers `a` and  `b` to be summed? Actually the concatenation works from right to left and the result above is absolutely correct. If we want to sum the numbers, we have to use **brackets**, in order to change the order of execution of the operations:
