### Why do you work problems in parenthesis first?

Parenthesis are grouping symbols () as well as brackets [] and
braces {}. These symbols are used specifically to denote that the
operation in the parenthesis should be completed first. This is to
avoid confusion and incorrect answers by using the standard order
of operations: Multiply and Divide, Add and Subtract.

### What is the rules of PEMDAS?

The rules of PEMDAS are 1. Parenthesis anything in them you do
first. 2. Exponents those little numbers next to the number telling
you to multiply the number by itself a certain number of times 3.
Multiplication and Division whichever comes first and 4. Addition
and Subtraction whichever comes first. If there is an exponent next
to parenthesis but there is no number that means the answer to the
parenthesis has to be the thing that the exponent is next to. All
of the rules apply inside of the parenthesis as well. If there is a
number next to the parenthesis not followed by a symbol multiply
the answer to the parenthesis by that number.

### What are brackets used for?

in math, they act just like parenthesis, to tell you to operate
on the terms inside the brackets, first. If you have several levels
of nested parenthesis, then using pairs of brackets [] and braces
{} help you to see which ones go together. This usually is only
used in handwritten problems, as most computer software only
recognizes parenthesis () to separate expressions.

### In parenthesis after paraphrased or quoted material in a research paper?

Yes, after you have paraphrased or included a quoted material in
a research paper, you must put in parenthesis the original author.
If you don't want to put it in parenthesis, you could include the
author's name somewhere in your sentence before quoting or
paraphrasing.
Example: John Locke said: "Don't tell me what I can and can not
do."
or
"Don't tell me what I can and can not do" (Locke).

###### Asked in Math and Arithmetic

### Which operation should be performed first according to the order of operations?

In a standard calculation it would be the exponent, also known
as the power of. However, the use of brackets can change the order
of operations and so sometimes another operation could be done
first.
Exponents should be processed first, then multiplication and
division, then addition and subtraction. The use of parenthesis
brackets can be used to override this default precedence order.
