Question

How do you simplify `\frac { ( 4\xx 5- 10) } { 2} + 4`?

Answer 1

This expression would be equal to `9`.

Explanation:

This problem can have many different answers, depending on how you work the problem. This is why there is a set order of operations for standardizing the method of finding an answer.

1. Parentheses
2. Exponents
3. Multiplication and Division
4. Addition and Subtraction

In your question, we must first determine the value of what is in the the parentheses. Since there are two terms, one with a multiplication and one subtraction, according to the order of operations, you must multiply first.

`(4xx5-10)` = `(20-10)` = `(10)`

Now that the parentheses are taken care of, you can now move down the list. There are no exponents, but there is a division problem. This is your next step.

`(10)/2` = `5`

Finally, you can move on to addition and finish the problem

`5+4` = `9`

If you follow this order, you are able to finish every problem correctly.

Answer 2

Use the order of operations

Explanation:

PEMDAS If you get hurt in PE class call an MD ASap
PE are parenthesis and exponents these must be removed first. In this expression remember that a division bar / acts as a parenthesis.
MD ( a medical doctor) is only one person so M multiplication and D Division must be done at the same time working from left to right.
AS(ap) ( As Soon as possible ) is one time so A addition and S subtraction must be done at the same time working from left to right .

Starting within the upper parenthesis `( 4 xx 5 -10)` the multiplication must be done first

`(4 xx 5 -10) = 20 -10 = 10`

Next the division bar must be dealt with acting as parenthesis

`(10/2 ) + 4 = 5 +4 = 9`
