Order of Operations in evaluating a mathematical expression

The order that we use to assemble a cake or build a house is important. The same holds true for evaluating any expression in math. We call this the Order of Operations. In your own words, explain the Order of Operations.

Give an example of an expression to fit this situation in math and an example in real life.

Please share any trick or mnemonic device to help you recall this order or how to use it. A mnemonic device is a memory trick such as using "The quick brown fox jumped over the lazy dog" to learn all the keys on the keyboard.

What I recall as a mnemonic device is the phrase "Pardon Me Dear Aunt Sally" which stands for

The order of operations in arithmetic is essential when you have to evaluate an expression that has more than one operation. Like the expression that solves this problem, for example:

Mike bought four boxes of candy, each containing 20 pieces from WalMart ...

Solution Summary

A mnemonic device is given for the order of operations in evaluating a mathematical expression.

I am confused with the concept of mathematicalexpressions. How can I tell when a collection of operations and numbers is an expression?
Is "234x + - รท 14 - 23 46 -" an expression? Can you help me understand this concept?
Thanks

What is the difference between an equation and an expression? Include an example of each. Can you solve for a variable in an expression? Explain. Can you solve for a variable in an equation? Explain. Write a mathematical phrase or sentence for your classmates to translate.

1. Why is it necessary to study the order of operations and the laws of operations before you start solving equations?
2. Of the three laws, commutative, associative, and distributive, which one is most frequently used in algebra? Why?
3. How does a term differ from a factor?
4. When adding or subtracting expressions,

Use multiplication, division, addition and subtraction and at least one set of parentheses to write an expression that simplifies to 7, 13, or 17. Do your work step by step and explain each step as you simplify the expression. Demonstrate the consequences of not using the proper order of operations by showing that other orders

For every postfix expression there exists a corresponding and uniquely defined infix expression that evaluates to the same number. The converse is not true. The infix expression a + b + c can be represented as either abc++ or ab+c+ in postfix. The reason for the ambiguity is the lack of brackets in the infix expression.
If th

Below are examples expressions for a variable. I need to explain my problem and answer just like the examples below, please give me a few problems to explain just like the samples below thanks...
A mathematicalexpression is similar to a phrase or fragment of a sentence. An expression has no subject and no verb or relatio

1. Suppose there is a program that reads a word and writes the reverse of the word to to output. For example, the program reads "faced" and writes "decaf". The program uses a stack to reverse the string. Please list all activation of the push and pop methods along with which letter is being pushed or popped at each step if the i
