WebIt is a special matrix, because when we multiply by it, the original is unchanged: A × I = A. I × A = A. Order of Multiplication. In arithmetic we are used to: 3 × 5 = 5 × 3 (The Commutative Law of Multiplication) But this is not generally true for matrices (matrix multiplication is not commutative): AB ≠ BA

WebWhen you multiply 2 (or 2/1) by 3/2, you multiply numerator by numerator, and denominator by denominator. You end up with 6/2. When you reduce (or simplify), you divide both the numerator and the denominator by their GCF (greatest common factor). 6/2 = 3, and 2/2 = 1. So you're left with 3/1, or 3. Now look back at your original problem, x • … WebThe basic idea of multiplying is repeated addition. Example: 5 × 3 = 5 + 5 + 5 = 15.
