Discussion Overview

The discussion revolves around basic arithmetic operations, specifically the expression "2 + 2/2" and the order of operations in mathematics. Participants explore the implications of this expression and clarify the rules governing arithmetic calculations.

Discussion Character

  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant asks about the educational background of another and expresses admiration for their understanding of mathematics.
  • Another participant calculates "2 + 2/2" as 3, citing the order of operations as the reason for this result.
  • A participant questions whether operations should be performed left to right, indicating a potential misunderstanding of the order of operations.
  • Another participant clarifies that operations are performed in a defined order rather than strictly left to right, addressing the previous question about the arithmetic process.

Areas of Agreement / Disagreement

There is some disagreement regarding the understanding of the order of operations, with one participant suggesting left-to-right processing while others emphasize the established rules. The discussion remains unresolved regarding the interpretation of these rules.

Contextual Notes

Participants reference the order of operations but do not fully explore the implications of potential misunderstandings or the context of arithmetic rules. There is a lack of consensus on the interpretation of left-to-right processing in arithmetic.

yo man u seem really really smart. i was wondering if u don't mind me asking where did u go to school and what did u major in. i love math, its fascinating, and u seem to have a very in depth understanding of it so if u don't mind could u tell me? also i don't have a question. 2+2/2 wahts the answer 2 or 3? there are no parenthesis i know that would change it.
 
Mathematics news on Phys.org
2+2/2 = 2+1 = 3

Why? Order of operations.

here's a way to remember...
Please Excuse My Dear Aunt Sally
P=Parentheses
E=Exponents
M=Multiplication
D=Division
A=Addition
S=Subtraction

In other words, first solve brackets, then parentheses, then multiplication/division, then addition/subtraction last.


In the case of "2 + 2/2"...
First: Division (2/2)
Second: Addition (2+1)

Thus, 2+2/2 = 3

You all look the same to me.

ah, a typo discovered i have. mb. also i thought that you were supposed to work left to right? isn't that a rule too? maybe I am just crazy.

No, you READ left to write (well, those of us of European linguistic bent). You do operations in the defined order as Brum said. As far as you being crazy- I wouldn't presume.
