Subtraction Strategies. Strategies are listed from the earliest strategies up through the standard algorithm. Many are used side by side, but it is important to understand that the variety of ...

Abstract: To improve the enhancement effect of noisy speech signals, this paper presents and analyses a new speech enhancement algorithm based on improved spectral subtraction. In contrast to the ...

The Common Core State Standards teach students the algorithm for multi-digit addition and subtraction in 4th grade. But some experts say it should be taught sooner.

Ellis showed a subtraction problem, performed both using the traditional regrouping, or borrow-and-carry, algorithm and using an example from the common core. Here’s a screenshot of the two methods.

Unfortunately, as proved by Avizienis, the standard algorithm for carry-free addition of SD numbers does not work for the binary case. In this paper, we therefore construct a special algorithm for the ...
