Guide
Standard mathematical expressions are evaluated in a specific sequence: parentheses first, followed by exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).
This expression solver parses the input values and groups them using standard rules, verifying that multiplication occurs after grouped addition.
PEMDAS
An acronym for Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Operator precedence
Rules defining which operators are evaluated first in an algebraic expression.
Without a standard sequence, the same mathematical expression could yield multiple different answers. Order of operations ensures every calculation is consistent.
It groups addition and multiplication using standard parentheses: (A + B) x C.
