If I were to compare -(-9)and -[-9] would it be less than, more than or equal to? I say it is equal to.
Would I be right?
Thank You for your help.
unless your ( bracket has a different meaning from the [ bracket, they are the same,
both equal +9 or plain ol' 9
Thank You Reiny, much appreciated. Could you tell Ms. Sue thanks for the heads up on the website math is fun, I have been learnign quite alot form it.
Thank You again.

You're welcome, Kyle. I'm glad that Math is Fun is so helpful. I learn from it all of the time.
To compare -(-9) and -[-9], let's simplify each expression step by step.
Starting with -(-9), we have a negative sign in front of a negative number. When we multiply two negative signs, it becomes positive. So, -(-9) simplifies to 9.
Next, let's simplify -[-9]. In this expression, we have a negative sign in front of the negative symbol, which means we're subtracting a negative number. When we subtract a negative number, it is the same as adding the positive value. So, -[-9] simplifies to 9.
Now that we have simplified both expressions, we can compare them. 9 and 9 are equivalent numbers, which means they are equal.
Therefore, you are correct! The expressions -(-9) and -[-9] are equal to each other.
