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.
What professions use order of operations?
No professions use order of operations. It is just a method of solving an equation.
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.
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).
How would you write - 36 divided by the sum of 9 and 3?
(-36)/(9+3) I would use parenthesis to execute proper order of operations.
