Answer:
The answer is 0.
Step-by-step explanation:
Now, here we have to find the value of the expression:
b + (-b)
So here when we open up the brackets, we will get:
b + (-b)= b -b
So we can see that the term b is subtracted from itself and hence we get:
b -b=0
So the final value of the given expression:
b + (-b)= 0
and this is true for any real number b.
