Answers to Questions (FAQ)
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/braces depend on the precedence of mathematical operators. Exponentiations precedence over multiplication and division have themselves priority over addition and subtraction.
To calculate the final result, use the dCode tools as the simplifier of mathematical expressions.
What are the rules for removing parentheses?
In mathematics, there exists an order for operators, a priority is given to some mathematical operations: (1: top priority, 4: lowest priority)
1 - calculations in parentheses
2 - exponentiations
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 are unnecessary and can be deleted.
Example: In the expression 1+(2*3), the multiplication is going to be computer before the addition, so parenthesis are useless.
How to simplify a negative parenthesis?
It is possible to get rid of some parentheses preceded 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
