Final answer:
The law of order and the law of grouping do not apply to subtraction.
Step-by-step explanation:
The law of order and the law of grouping do not apply to subtraction.
The law of order, also known as the commutative property, states that changing the order of numbers being added or multiplied does not change the result. However, subtraction does not satisfy this property. For example, 5 - 3 is not the same as 3 - 5.
The law of grouping, also known as the associative property, states that changing the grouping of numbers being added or multiplied does not change the result. Again, subtraction does not follow this property. For example, (7 - 4) - 2 is not the same as 7 - (4 - 2).
