The operation is P.E.M.D.A.S., and each letter stands for an operation to use. P - parentheses, E - exponents, M - multiplication, D - division (multiplication and division are equal...so it doesn't matter which direction it is in. This is the same for addition and subtraction), A - addition, S - subtraction. I hope this helped :-)

You use order of operations in equations that have more than one type of operation going on (for example, an equation with parenthesis, addition, and multiplication). You would use order of operations in equations like that so you know which operation to do first.

No professions use order of operations. It is just a method of solving an equation.

Because if you perform the operations in a different order your answer will be wrong.

Yes, and parenthesis are the first thing you solve.

It is convenient for different people to agree on the standard order of operations. This saves complicated explanations.

solve the top and bottom first

You use order of operations in equations that have more than one type of operation going on (for example, an equation with parenthesis, addition, and multiplication). You would use order of operations in equations like that so you know which operation to do first.

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.

We have to use the order of operations so everyone solves a problem the same.

how do you use order of operations

No professions use order of operations. It is just a method of solving an equation.

3+4x2, this simple example can produce answers 14 (if addition was done first and multiplication done afterwards) or 11 (if multiplication was done first and addition was done subsequently). This is just a simple example. Mathematics is a precise science and to get the answer universally correct (without any ambiguity) a set of rules (or conventions) are established. In order of decreasing priority we evaluate what is enclosed in parentheses, then exponentiation, Multiplication/Division, Addition/Subtraction etc. The left to right rule is used when operation of same strength are encountered. If logical operations are involved (as in computer operations) then those operations also have set priorities. Thus the order of operations is used by mathematicians to ensure consistency.

You don't.

its -17 i think but other than that i agree that the fact i in 6th grade only 11 and answering this.

Use brackets or parentheses.
