The Standard Multiplication Algorithm - Homeschool Math

WebThe grade-school integer multiplication algorithm. In this naive algorithm, the total number of operations is 3 (3 operations per row for multiplication and addition)· 3 (3 rows in total) = 9. Thus, roughly the running time estimation is с ⋅ n 2, bounded by Ο(n 2). 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 requires 310= 59,049 thus being ~17.758 times faster.
