What is a grouping in math example?
In mathematics, a group is a kind of algebraic structure. A group is a set with an operation. The group's operation shows how to replace any two elements of the group's set with a third element from the set in a useful way. A familiar example of a group is the set of integers with the addition operation.

What does a fraction bar mean in order of operations?
divisionAlthough the fraction bar represents division, it is a very powerful idea to see it as a grouping symbol as well. With enough practice, this will become second nature. EXAMPLE 1. 15−2⋅37−4.
