−75 − (−75)
When we subtract a negative number from another negative number, it is equivalent to adding their absolute values.
Therefore,
-75 - (-75)
= -75 + 75
= 0
So, -75 - (-75) is equal to 0.
To simplify the expression −75 − (−75), you can follow these steps:
1. Start by simplifying the inner parentheses, which is the expression −75. Since there is a negative sign in front of it, you can change its sign by multiplying it by -1:
−75 * -1 = 75
2. Now replace the expression inside the parentheses with the simplified value:
−75 − (−75) = −75 - 75
3. Subtract the two values -75 and 75:
−75 - 75 = -150
Therefore, −75 − (−75) simplifies to -150.
