Question

a-(b-c)=a-b-c

think it is true or false"
and give solution why it is true or false?

Answer 1

Answer:

False

Step-by-step explanation:

If b is multiplied by the minus sign outside the bracket the answer we will get is (-b), because of the formula (-) × (+) = (-).

And because we have a whole bracket multiplying with the minus sign (-c) will change to (+c) because of the formula

(-) × (-) = (+).

Hence, a-(b-c) = a-b+c.
