To help you understand the algorithm, the video shows a simple two-digit by two-digit multiplication. You can see that the first and last digits are essentially the result of one multiplication.

The second (and much more difficult) part of their conjecture is that N log (N) should be the fundamental speed limit—that no possible multiplication algorithm could do better than this.

Karatsuba’s divide-and-conquer multiplication algorithm takes advantage of this saving. Consider a multiplication algorithm that parallels the way multiplication of complex numbers works.

You wouldn’t use this algorithm when calculating a tip, but when it comes to multiplying large numbers, Karatsuba’s method was a big advance. And once Karatsuba opened the door to faster ...

What do encrypted messages, recognizing speech commands and running simulations to predict the weather have in common? They all rely on matrix multiplication for accurate calculations. DeepMind, an ...

Quantum computers can’t selectively forget information. A new algorithm for multiplication shows a way around that problem.

Learn what an algorithm is with this KS1 primary computing guide from BBC Bitesize for years 1 and 2. We will define what an algorithm is and how they work.

AI engineers develop an algorithm that will replace floating-point multiplication with integer addition to make AI processing more efficient.
