1. Parentheses (Brackets)
Expressions inside parentheses are solved first.
Example:
(6 + 4)
2. Exponents (Orders)
Powers are evaluated next.
Example:
5²
or
5^2
3. Multiplication and Division
These are solved from left to right.
Example:
18 ÷ 3 × 2
4. Addition and Subtraction
Solved from left to right after multiplication and division.
Example:
8 + 12 − 5
Following this sequence guarantees accurate results.
Formula Behind the Calculator
Unlike calculators that use one single formula, an Algebraic Calculator evaluates expressions according to mathematical precedence.
General expression:
Result = Evaluate(Expression)
Where the expression may include:
