Which of the following illustrate the commutative property? select all that apply

Genrish500 [490]

For this case we have that the commutative property establishes that the order of the factors does not alter the product. Example:

$5 * 6 = 6 * 5\\4 + 3 = 3 + 4$

Then we have the following options illustrate the property:

$3 + 4 + 6 = 3 + 6 + 4 = 13\\9 * 2 * 7 = 7 * 9 * 2 = 126\\2 + 3 + 1 = 3 + 1 + 2 = 6\\5 + 2-4 = 5-4 + 2 = 3$

It is necessary to emphasize that option b illustrates the associative property and in option c equality is not fulfilled

Answer:

Option A, D, E, F
