Multiplying Any Two Digits Numbers In 3 Seconds 2 Digits Fast

Multiplying Any Two Digits Numbers In 3 Seconds 2 Digits Fast In this math trick video we look at an easy way to multiply numbers where the ten’s digit is the same and the one’s digit adds up to 10. example: to find 52 × 58. take the ten’s digit and multiply it by the next highest number. 5 × 6 = 30. next, multiply the one’s digit. 2 × 8 = 16. the answer is 3016. Here are the things to practice: (1) to compute x2 x 2: use the identity x2 = (x a)(x − a) a2 x 2 = (x a) (x − a) a 2, with a a chosen to make x a x a as round as possible. this is especially fast for numbers near to 50 50 or 500 500 or 5000 5000 and so on.

In long multiplication, we have to multiply every digit of the first number by every digit of the second number. if the two numbers each have n digits, that’s n2 (or n x n) multiplications. To multiply two numbers with 1 billion digits requires 1 billion squared, or 10 18, multiplications, which would take a modern computer roughly 30 years. for millennia it was widely assumed that there was no faster way to multiply. then in 1960, the 23 year old russian mathematician anatoly karatsuba took a seminar led by andrey kolmogorov, one.
