Three Digit By Two Digit Multiplication Worksheets Made By Teachers Matrices for class 12 – notes. question 4: let x, y, z, w and s be matrices of order 2 × n, 3 × k, 2 × p, n × 3 and p × k, respectively. find the values of n, k, and p so that sy wy is well defined. solution: order of s = p × k. order of y = 3 × k. if the matrices s and y are multiplication conformable, then k = 3. To multiply a matrix by a single number is easy: these are the calculations: 2×4=8. 2×0=0. 2×1=2. 2× 9= 18. we call the number ("2" in this case) a scalar, so this is called "scalar multiplication". Definition 2.2.3: multiplication of vector by matrix. let a = [aij] be an m × n matrix and let x be an n × 1 matrix given by a = [a1⋯an], x = [x1 ⋮ xn] then the product ax is the m × 1 column vector which equals the following linear combination of the columns of a: x1a1 x2a2 ⋯ xnan = n ∑ j = 1xjaj. (8 ÷ 4) ÷ 2 ≠ 8 ÷ (4 ÷ 2) and (5 4) 3 ≠ 5 (4 3) division and subtraction of numbers is not associative; matrix multiplication is associative (ab)c ≡ a(bc) to multiply three matrices together, it's fine to start by multiplying the first two together, or to start by multiplying the second two together. just don't switch the order.
