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.ฤก) 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.
