The library adds new type of rational numbers and basic math operations for them. Rationals can also interact with integers and floats. Actually this library expands existing functions, so they can ...

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 ...

After your student has mastered the basic math facts, it is time to move on to rational numbers; Hooda Math has you covered with Factor Feeder, Fraction Poker, and Integer Tilt 2. To make math ...

It’s surprisingly difficult to prove one of the most basic properties of a number: whether it can be written as a fraction. A broad new method can help settle this ancient question. In June 1978, the ...

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 ...
