• It states that the order of the factors does not change the product, that is, it does not matter if you multiply 7 × 5 or 5 × 7, the result will always be the same, 35.
• Thus, it may be that the multiplication table that was so hard for us to memorize is no longer so difficult because we can change the order of the factors and, 7 × 5, it is not as difficult, because the table of five is easier: 5 × 7 = 35.
