SUMMARY

The discussion centers on the mathematical expression "2 + 2/2" and the application of the order of operations, commonly remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). The correct evaluation of the expression is established as 3, following the order of operations where division is performed before addition. Participants clarify misconceptions about left-to-right reading and emphasize the importance of adhering to the defined operational hierarchy.

PREREQUISITES
  • Understanding of basic arithmetic operations
  • Familiarity with the order of operations (PEMDAS)
  • Basic knowledge of mathematical expressions
  • Ability to interpret and evaluate mathematical problems
NEXT STEPS
  • Study advanced arithmetic operations and their applications
  • Learn about mathematical expressions and their evaluation
  • Explore common mathematical misconceptions and how to address them
  • Investigate the history and development of mathematical notation
USEFUL FOR

Students, educators, and anyone interested in enhancing their understanding of arithmetic and the order of operations in mathematics.

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.
