Answers to Questions

How and when to remove parentheses?

Enter a mathematical expression including parentheses and click on the button. If unnecessary or redundant parentheses are detected then the expression can be simplified (visually).

Example: ((a*b)+(c*d)) can be rewritten without parenthesis in a*b+c*d

Example: (a+b)*(c+d) can not be simplified

The rules to remove the parentheses are simple and depend on the precedence of mathematical operators. Exponentiations precedence over multiplication and division have themselves priority over addition and subtraction.

What are the rules for removing parentheses?

In mathematics, there is an order for operators:

1 - calculations in parentheses

2 - exhibitors

3 - multiplications and divisions

4 - additions and subtractions

The only necessary parentheses are those that require a different order in the calculation of an expression. The others can be deleted.

How to simplify a negative parenthesis?

It is possible to remove some parentheses preceeded by a - sign. Indeed, the subtraction operation equals the addition of the opposite.

Example: 'a-(b+c) is equivalent to a+(-b-c) or a-b-c
