CHAPTER 03.08: BINARY OPERATIONS: Product of a scalar and a matrix Example

In this segment what we’re going to do is going to take an example of how to find a product of a scalar and a matrix. Let’s suppose somebody says given a matrix A as follows: 2.1, 3, 2, 5, 1, 6 and says find 1.1 times A. So all we have to do is in order to be able to do that so if we want to find 1.1 times A, all we have to do is to multiply each element of A by 1.1. I’ll take three and multiply it my 1.1, 2 times 1.1, 5 times 1.1, 1 times 1.1, and 6 times 1.1. And what will that be equal to? That’ll be equal to, so I have to do these multiplications, so 11.1 is 11 and two is a twenty two so its 2.31, that’ll be that one. This one will be 3.3, this one will be 2.2, this one will be 5.5, this one will be 1.1 and this one will be 6.6. So that’s the result of this multiplying this A matrix by a scalar of 1.1, this is what we get. And that’s the end of this segment.
