Students have a great deal of difficulties learning about rational number concepts, as they are confounded by misapplying reasoning about natural numbers to fractions and decimals, referred to as a natural number bias. For example, students often think that the number of digits of a decimal, or...
Arbitrary precision rational number class Here is the class signature, so you can see what it supports, but suffice it to say it supports all the typical arithmetic operations one would expect from an arithmetic class library. public class BigRational : IComparable, IComparable, IEquatable { /...
Using multigroup latent class analysis, the present study examines the structure of 611 Finnish and Flemish students' rational number knowledge in order to determine the similarities and differences between these two sub-samples. Results reveal that, while the Flemish students performed somewhat better,...
We determine the number of -rational points of a class of Artin–Schreier curves by using recent results concerning evaluations of some exponential sums. In particular, we determine infinitely many new examples of maximal and minimal plane curves in the context of the Hasse–Weil bound. 关键词:...

We avoid finite-size effects by tessellating in-plane \({l}_{{{\bf{e}}}_{1}}={l}_{{{\bf{e}}}_{2}}=7\) unit-cells along the base vectors {e1, e2} and stacking n = 6 layers (see Fig. 5a and Supplementary Discussion“Experiments”). A generic tessellated system ...

Lactacystin exemplifies the role that serendipity plays in drug discovery and why “finding things without actually looking for them” retains such a pivotal role in the search for the useful properties of chemicals. The first proteasome inhibitor discov
