Answer 2

Answer:

The expressions that are equal to 6 are:

                       (6) , -(-6)

Step-by-step explanation:

We are asked to find the expressions which are equal to 6.

a)

          (6)

We know that on opening the parentheses term if the sign before the parentheses is positive then the number remains the same.

but if the sign before the parentheses is negative then the number gets reversed.

Hence, the number is equal to 6.

b)

         (-6)

The number is equal to -6.

c)

          -(6)

The number is equal to -6.

d)

           -(-6)

The number is equal to 6.

e)

          (0-6)

The number is equal to -6.

f)

    (-2) · (3)

The number is equal to -6.

( We know that the multiplication of a negative and a positive number is always a negative number ).
