In algebra problems, parentheses, brackets, and braces are all used for grouping. Terms inside the grouping symbols have to be operated upon before they can be acted upon by anything outside the grouping symbol.
All the grouping types have equal weight; none is more powerful or acts differently from the others. If the problem contains grouped items, do what’s inside a grouping symbol first, and then follow the order of operations. The grouping symbols are ✓ Parentheses ( ): Parentheses are the most commonly used symbols for grouping. ✓
Brackets [ ] and braces { }: Brackets and braces are also used frequently for grouping and have the same effect as parentheses. Using the different types of symbols helps when there’s more than one grouping in a problem. It’s easier to tell where a group starts and ends.
It may be a difficult process to figure out, but there are several ways to make sure that you are not paying too much for your goods and services. This is very common and is sometimes referred to as new things you want to be unique.
