To multiply two numbers by hand takes a few steps but it's something we're taught in school. When dealing with big numbers, really big numbers, we need to a quicker way to do things.

So when it comes to measuring the efficiency of a multiplication algorithm, it’s the small multiplications that concern us most. Let’s revisit our example, 25 × 63, with efficiency in mind. In order ...

The Schönhage–Strassen algorithm, developed by two German mathematicians, was actually the fastest method of multiplication from 1971 through 2007.Although a faster method was developed in 2007 ...

Mathematicians have reportedly discovered a new way of multiplying two numbers together. The new technique is for really large numbers, and if it passes a peer-review, could be the fastest ...

Still, be sure to also teach students the common denominator approach, since they don’t need to flip and multiply fractions in order to divide and conquer them.

A pair of researchers have found a more efficient way to multiply grids of numbers, beating a record set just a week ago by the artificial intelligence firm DeepMind.. The company revealed on 5 ...

In this case, AlphaTensor discovered an algorithm for multiplying 4 by 4 matrices in just 47 multiplications, thereby improving on Strassen’s 50-year-old two-level algorithm, which uses 49 ...
