Vectors: Operations

Adding, Subtracting, and Multiplying Vectors is easy from the looks of it, As you look at the image up there, Vectors are quantities or fixed points, and takes the shape of; for an example, A (with an arrow on top of it) = <5,4>; 5 represents X1 and 4 represents Y1 and there will usually be a second fixed point and its first term represents X2 and the second term represents Y2.

As for Adding, Lets look at the example in the image above, here we have a = <-4,-3> and c = <1,-2>, to add them you need to note that the first Number in each vector represents X and the second Number in each vector represents Y, so we are going to add the X's together, which are -4 and 1, and the Y's togther, which are -3 and -2, the model to add looks like this: <-4 + 1 , -3 + (-2)> , which equals <-3 , -5>, and that is your fixed point ready, for the subtraction it will look like: <-4 - (1) , -3 - (-2)>, and the result will be <-5 , -1>, and if it is Multiplication, it will look like: 3<-3,-5>, you will need to multiply the number outside with Numbers in the vector; the result is <-9,-15>.

Notes: Keep an eye to the signs when Subtracting
Add the X's together alone and the Y's together alone.
