Interactive FAQ
What is the order of operations?
PEMDAS/BODMAS is an acronym that helps remember the order of operations: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
How do I simplify a fraction?
To simplify a fraction, find the greatest common divisor (GCD) of the numerator and denominator, then divide both by the GCD.
