Most of us rely on the "carrying method" when we multiply. But there's a much faster way to handle large numbers.

Matrix multiplication - where two grids of numbers are multiplied together - forms the basis of many computing tasks, and an improved technique discovered by an artificial intelligence could boost ...

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 ...

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.

Multiplication of two numbers is easy, right? At primary school we learn how to do long multiplication like this: The long way to multiplication. David Harvey Methods similar to this go back thousands ...

But is this really the best way to multiply two big numbers together? In long multiplication, we have to multiply every digit of the first number by every digit of the second number.
