Question

Simplify: −(−(−78))
Write answer in numerical value

Answer 1

-78

Explanation:

We need to find the value of -(-(-78))

We know that, -(-x) = +x

And -(-(-x)) = -x

We have,

x = 78

When two minus gets multiplied, we get a positive number and when a minus and a plus gets multiplied, we get a negative number. So,

-(-78) = +78

And

-(-(-78)) = -78

So, the numerical value is -78.
