Question

A - ( - b - c - d ) + ( - c + f )

Answer 1

а - ( - b - c - d ) + ( - c + f )=а+b+c+d-c+f=a+b+d+f

Answer 2

To simplify this expression, we can first simplify the terms inside each set of parentheses, using the distributive property of multiplication over addition/subtraction:

-(b + c + d) = -b - c - d -(c + f) = -c - f

So the expression becomes:

A - ( -b - c - d ) + ( -c + f )

= A + b + c + d - c - f

= A + b + d - f

Therefore, the simplified expression is:

A + b + d - f
