In this math lesson, we’ll talk about “Parentheses” “( )”
In math questions, parentheses are setting aside some few terms or operations.

The whole idea of parentheses is that they say, “Do this thing first!”
Sometimes, parentheses are hugely important for the order of operations. The answer to the question may be totally depending on them.
Sometimes, parentheses will help you to see where you should start but are not playing an important role in coming up with the right solution. So let’s look at some ways in which parentheses may be used:
A few examples:
(1 + 2) + 3 = 3 + 3 = 6
3 + (9 x 2) = 3 + 18 = 21
(3 * 6) + (5 – 2) = 18 + 3 = 21
Well, you were introduced to parentheses. You must do the math issue within the parentheses first. And when you’ve got that stuff inside out of the way, move on to the operations that are in the question’s open areas.
Even when they’re inside the parentheses, you first need to complete the operations of multiplication and division.
If you’re confronted with multiple operations, the very last steps you need to are addition and subtraction.
In the previous paragraph, I told you most of the “parentheses” story. So you begin with the parentheses, then move on to multiplication and division, to finish with addition and subtraction.
