Students calculators
Tools to ace your studies: weighted average, grade needed to pass, LCM and GCD, fractions, powers and roots. TudoCalc's student calculators show the steps, not just the answer.
Quadratic formula
Solve quadratic equations (ax² + bx + c = 0) with the delta and roots step by step.
LCM & GCD
Calculate the least common multiple (LCM) and greatest common divisor (GCD) of two numbers.
Grade needed
Find out the grade you need on the final exam to reach the required average.
Grade calculator

Linear equation
Solve first-degree equations in the form ax + b = c, with a check of the result.
Fraction
Add, subtract, multiply and divide fractions, with the result already simplified.
Power & root
Calculate powers (base raised to an exponent) and roots (square and nth).
GPA
Calculate your GPA on the 4.0 scale from letter grades and credit hours per course.
Weighted average
Calculate the weighted average from values and their corresponding weights.
