Question

Jerome tries to find the value of the expression 3 - 6 + 5 by first applying the commutative property he rewrites the expression as 3 - 5 + 6 explain what is wrong with Jerome approach

Answer 1

• Wrong in sign change

How?

• In commutative law the sign doesn't change whenever it is applied.

Thus

`\\ \sf{:}\implies 3-6+5`

`\\ \sf{:}\implies 3\underline{+5-6}`

`\\ \sf{:}\implies 8-6`

`\\ \sf{:}\implies 2`
