Question 758829: what is [ used for in a algebra problem?

You can put this solution on YOUR website! Brackets are recommended to be used when dealing with more complicated algebraic problems.
For example: [(4-6)+(6+8)]*3
A problem such as this will tell you to add and subtract within the parentheses before multiplying with three. The operation would look something like this:
[(-2)+(14)]*3
[12]*3
=36 *check*
