Juan used the expression 16 – 9 – 12 + 22 to find his profit for days 2 and 3. He rewrote the expression as 16 + (–9) + (–12) + 22.
Juan can use the associative and commutative properties to rewrite the expression again. Explain why he had to use the additive inverse before he could use these properties.
Answer: The associative and commutative properties can be applied only to problems with addition. Juan had to change the subtraction to addition by adding the additive inverse.
This is the answer hope ur happy!

Answer:
Read the poem and answer the following questions.
[1x6=6]
Five Little brothers set out together
To journey the live long day,
In an odd little carriage, all made of leather,
They hurried away, awayOne big brother and three quite small,
And one wee fellow, no size at all.
The Carriage was dark and none too roomy,
And they could not move about;
The five little brothers grew very gloomy,
And the wee one began to pout;
Till the biggest one whispered: “What do you say?
Let’s leave the carriage and run away.”
1. What is 'the carriage of leather' in the poem?
2. Who were the five little brothers?
3. Write the rhyming words of these words
Associative and Commutative properties are applicable for Addition not on subtraction that's why additive inverse used to have all terms in addition,
Associative and Commutative properties are applicable for Addition and multiplication
These property are not for Division and subtraction
Commutative property of Addition
a + b = b+a
Associative property of Addition
a + (b + c) = (a + b) + c
a - b = b - a does not hold true until a = b
Hence Commutative property can not be applied on subtraction.
Similarly
Associative property can not be applied on subtraction
That's why additive inverse used to have all terms in addition,
So that Associative and Commutative properties can be applied
Associative and Commutative properties are applicable for Addition not on subtraction that's why additive inverse used to have all terms in addition,
