Understanding Order of Operations
The calculator follows standard mathematical precedence rules.
1. Parentheses First
Calculations inside parentheses are evaluated before other operations.
Example:
(5+3)×2
Result:
16
2. Exponents
Powers are calculated after parentheses.
Example:
3²
Result:
9
3. Multiplication and Division
These operations are performed before addition and subtraction.
Example:
2+4×3
Result:
14
4. Addition and Subtraction
These are evaluated last.
Example:
10−2+5
Result:
13
Following these rules ensures every result is mathematically correct.
