The browser used for posting questions on this site is rubbish. It is quite useless for mathematics since it strips out most symbols so that we cannot tell what the question is meant to be.
However the basic rule for English speaking countries is given by the mnemonic BIDMAS. Thisimplies
- Brackets
- Indices
- Divisions and Multiplications (on par, order from left to right)
- Additions and Subtractions (on par, order from left to right).
For American speakers, the mnemonic is PEMDAS, for
- Parentheses
- Exponents
- Multiplications and Divisions (on par, order from left to right)
- Additions and Subtractions (on par, order from left to right).

How are the order of operations and combining like terms are used to simplify expressions?
They are used to simplify expressions by helping to reduce the numbers that there is
How do you evaluate an expression with more than two operation symbol without exponent and parenthesis?
In Evaluating Expression first,replace each letter in the expression with the assigned value. second,perform the operations in the expression using the correct order of operations and the last you got the answer
Why is it important to apply order of operations when evaluating expressions?
If you change the order of operations, you will get a different result. The person who wrote the expression had a specific order of operations in mind (using generally-accepted rules), so arbitrarily using some other order of operations is, quite simply, wrong.
How does the order of operations affect the value of an expression?
because they can affect us by thinking how wrong we are to be .. so that many people can encourage that order of operations affect us in real life .
What is the Order of Operations that governs what is done first when evaluating an numerical expression that involves two or more operations?
When evaluating an expression, do these in this order:work out what is inside any parentheses firstnext, do exponentsmultiplication and division are done in the order you see them, from left to right.addition and subtraction are done in the order you see them, from left to right.
In math how do you simplify an expression?
Math can be difficult at times. To simplify a math expression, it is important to follow the order of operations, or PEMDAS.
How can you evaluate a expression?
replace the variables with the given values and simplify using the order of operations.
Why mathematicians had to agree on an order of operations to be used to simplify a numerical expression?
It has nothing to do with agreement or negotiation. There's only one order of operations that leads to the correct outcome.

1. 2Explain how to write and evaluate an algebraic expression.thirteen less than the quotient of forty and a number; evaluate when n = 2?
Sample Response: Replace key words with variables, numbers, and operations. Less than is subtraction, and quotient is division. Order matters with subraction and division. The expression is 40 n -13. To evaluate is the expression, substitute 2 in for the variable, and then use order of operations to simplify. The value when n = 2 is 7. Check any that you included in your response. a. Replace key words with variables, numbers, and operations. b. Less than means subtraction, and quotient means division. c. Order matters with subtraction and division. d. The expression is StartFraction 40 Over n EndFraction minus 3 – 13. e. To evaluate the expression, substitute 2 in for the variable, and then use order of operations to simplify. f. The value when n = 2 is 7. Select ALL of the above.
