# What is the order in which operations are done when finding the value of an expression with more than an operation?

The usual rule in algebra is to first do all multiplications and divisions from left to right; then all additions and subtractions, also from left to right. This order can be changed with parentheses - anything within parentheses should be evaluated first.

After parentheses and before the rest (as listed above), exponents should be evaluated. In summary, the proper and full order of operations is:

1. Parentheses
2. Exponents
3. Multiply and divide

A commonly-used acronym to remember this order is: PEMDAS (Please Excuse My Dear Aunt Sally).

### Why did mathematicians have to agree on an order of operation 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.

### 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.

### 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 do you solve first in the order of operations and why?

partheses because that the first order of operation

### Who is the first person invent pemdas?

There is no known origin of the order of operations or PEMDAS. PEMDAS is considered as the proper way to tackle a given mathematical expression in terms of what operation should be performed first.
