When my students grow too dependent on their calculators, I ask them to find a number that, when multiplied by itself, gives them 2. Students quickly see that since 1² = 1 and 2² = 4, the answer has ...

Rational numbers are those that can be expressed as a fraction of two integers, where the denominator is not zero. Rational numbers include fractions, decimals, and mixed numbers. Recognizing rational ...

This is an open-source C++ algorithm to compute Q-rational points on an elliptic curve defined over the field Q. To support the algorithm, a library of integers with arbitrary length and rational ...

An eminent mathematician reveals that his advances in the study of millennia-old mathematical questions owe to concepts derived from physics. Mathematics is full of weird number systems that most ...

A fraction n/d, where d is at most a given limit l, is the best rational approximation to a target real number t if the absolute difference (the absolute error) between n/d and t is the smallest among ...

An animated journey into the world of rational numbers! A fraction thief disrupts a number town, leading to a fun exploration of fractions, natural numbers, and mathematical concepts. Donald Trump's ...
