Question

Jerome tries to find the value of the expression 3-6+5 but first applying Community property. He writes expression as 3-5+6. Explain what’s wrong with Jerome’s approach

Answer 1

Nothing, its perfectly fine.

Answer 2

Answer:

Below.

Step-by-step explanation:

You mean the Commutative property.

What is wrong is that Jerome should have moved the + sign with 5 and left the - sign with the 6.

3 - 6 + 5

Moving the '+ 5' to before the '- 6' we get

3 + 5 - 6.
