Question

(2 − 3)(1 − ) − (3 − )(3 + )

Answer 1

your equation is wrong!! the answer is
`10`

Explanation:

the correct order of the equation is:

`(2-3)(-1)-(-3)(3)`

first, solve in the parentheses from left to right:

`(2-3)(-1)-(-3)(3)=\\(-1)(-1)-(-3)(3)=\\1-(-3)(3)=\\`

If we have 2 negative signs then we will change them to positive :

`1-(-3)(3)=\\1+3(3)\\`

now we have an equation with parentheses, we will multiply
`3(3)\\` because the parentheses go first.

`1+3(3)=\\1+9=10`
