A scalar is just a number, like 1, 2, or 3.In scalar multiplication, we multiply a scalar by a matrix.Each element in the matrix is multiplied by the scalar, which makes the output the same shape as the original matrix.
WebSo we multiply the length of a times the length of b, then multiply by the cosine of the angle between a and b OR we can calculate it this way: a · b = a x × b x + a y × b y So we multiply the x's, multiply the y's, then add. Both methods work! And the result is a number (called a "scalar" to show it is not a vector).
