WebOct 18, 2024 · To solve the problem, most people are taught to multiply each individual number together, and then add up the sums: 9 is multiplied by 4, 1, and 3; then 5 is multiplied by 4, 1, and 3, and so on ...
WebThe grade-school algorithm for multiplying two numbers xand y is to create an array of intermediate sums, each representing the product of xby a single digit of y. These values are appropriately left-shifted and then added up. Suppose for instance that we want to multiply 13 11, or in binary notation, x= 1101 and y= 1011. WebFor example, to multiply two 1024-digit numbers (n= 1024 = 210), the traditional algorithm requires (210)2= 1,048,576 single-digit multiplications, whereas the Karatsuba algorithm …
