How do you decide what operation you use to solve a problem?

Use BIDMAS meaning order of operations are brackets, indices, division, multiplication, addition and subtraction


When do you use order of operations?

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.


Why is it important to use order of operation?

you need to because if you follow the order of operations then you will get the question correct. If you don't then you won't. Simple as that


Why do you use the order of operations?

We use the order of operations as a method of solving mathematical equations containing three or more operation symbols. The order of operations help us to solve certain segments of the equation before adding it all together to find out what the final answer is.


What is the defenition of order of operations?

If you are speaking of Algebra, the order of operations is know as PEMDAS P=PARENTHESE E=EXPONETS M=MULTIPLY D=DIVIDE A=ADD S=SUBTRACT In order to solve an equation you must use this operation, if not you will not get the answer.

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.


Why do you have to use order of operations for every problem?

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


When do you use order of operations in real?

You don't.


How do you multiply integers using Pemdas operation?

PEMDAS is an acronym of the order in which operations must be carried out: Parentheses, Exponents, Multiplication, Divisin, Addition and Subtraction. You cannot use PEMDAS to multiply, since it is not an operation. give an example.

What can you use to control the order of operation in a formula?

The use of parentheses allows you to control, or change, the regular order of operations. For example, if you have the expression 4 + 2 * 3, under the normal order of operations, you would perform the multiplication before the addition. To perform the addition first, you just add parenthesis so the expression reads (4 + 2) * 3 instead.


Performing of operations on series of numbers?

An operation on a series of numbers is when you use amongst others addition, subtraction, multiplication and division. Mathematics decided the order of operations is to work out the sums in the brackets first, then exponents, then multiplications and division and finally addition and subtraction.


What is the order of operations in math?

It is something you use in math to answer questions that have more than one operation and more than two parts of a problem(ex.2+7 you can't use the order of operations for,(5/8)6+7,you can use this though).The way to remember the order is PEMDAS(parenthesis,exponents,multiply,divide,add,subtract)But go left to right when you do multiply/divide and add/subtract


Is order of operations useful?

Yes. Basically, you get different results if you use a different order.


Why do you use order of operation?

A standard order of operations lets you know which part of the equation gets calculated first. Without a standard order, someone might calculate 2 + 3 * 4 differently from 4 * 3 + 2, getting 20 in the first case and 14 in the second (by the way, 14 is the correct answer for both by the commonly accepted order of operations).


What role does Order of Operations play in simplifying algebraic expressions What would happen if we didn't use order of operations?

The order of operations defines, in the absence of parentheses, the order in which binary operations in arithmetic (or algebra) may be carried out. If it were not used, most expressions with more than one kind of operation would have more than one answers. Alternatively, each expression would have to have a parentheses to indicate the Order of Operations and that would make expressions more difficult to read. eg 2+3*5 = 2+15 = 17 (following Order of Ops), but 2+3*5 = 5*5 = 25 (NOT following Order of Ops).
