The Order of Operations in Expressions
Definition of Operator Precedence
Operator precedence refers to the rules that determine the order of evaluation for operators in an
expression.
Importance in Expressions
Understanding operator precedence is crucial for correctly interpreting mathematical and logical
expressions.
Example of Precedence
In the expression 2 + 3 * 4, multiplication is performed before addition due to higher
precedence of the multiplication operator.
Result of the Example
The evaluation of 2 + 3 * 4 yields 14, as multiplication is executed before addition.

Understanding the Significance for Programmers
% Unexpected results in calculations
Incorrect operator precedence can lead to
errors in mathematical results, affecting
overall program accuracy.
Increased debugging time
Misunderstanding operator precedence often
results in bugs that require additional time to
identify and fix.
Clarity in code
Mastering operator precedence
enhances code clarity, making it easier
for others to understand and
collaborate.
Ensuring intended performance A
solid grasp of operator precedence
guarantees that the code performs
as intended, producing reliable
outcomes.
Difficulties in maintaining code
Code with unclear operator precedence is
harder to read, making maintenance and
updates challenging.

Understanding Operator Associativity
Definition of Operator Associativity Operator
associativity defines the evaluation order of
operators with the same precedence level.
Importance of Associativity
It is crucial for correctly interpreting
expressions in programming and mathematics.
Evaluation Direction
Associativity determines if operations are performed
from left to right or right to left.
Example of Left Associativity
In the expression ‘ 10 - 5 + 2 ‘, both operations are
evaluated from left to right.
