![]() ![]() ![]() On paper this way of multiplying looks more complicated but with slight practice it becomes apparant that it's much quicker. We could think of every ' $=$' sign as a mental step.Ģ) The second method comes from a branch called Vedic math. With this method you have to memorize the problem, then the outcome of the first multiplication, then do the second multiplication and remember all outcomes in order to add them together. It immediately becomes clear that this method takes too long and can turn into quite a complicated mess, because you have to quickly combine non-trivial multiplication and addition. Then multiply the remaining $3$ with our right factor and add it to the result above, yielding:.First simplify the left factor and multiply it with the complete right factor, yielding:.Using this method on our example exercise would mean we take the following steps: It finds the answer by brute force multiplication and addition. I think this is the first method of multiplying that everyone learns. ![]() I will go over multiple methods that I know for computing this mentally, and explain my problems with each of them.ġ) The elementary method. The goal is to have someone tell you a problem and then, without having them repeat the problem, computing the answer. I have been doing some research into what the quickest way to computing the outcome of such a multiplication is but I still find myself having to go through too many steps in my head for each exercise. So I've been practicing alot of mental math recently and ofcourse as a part of that, multiplying a double-digit number by another double-digit number. ![]()
