+You can apply mathematic operations to numbers using some basic operators like:
 
 * **Addition**: ```c = a + b```
 * **Subtraction**: ```c = a - b```
 * **Multiplication**: ```c = a * b```
 * **Division**: ```c = a / b```
 
-You can use parentheses just like in math to separate calcul execution: ```c = (a / b) + d```
