Comparing −(−9)-(-9) and ∣−9∣|-9|

To establish the relationship between −(−9)-(-9) and ∣−9∣|-9|, simplify both numerical expressions independently. The notation −(−9)-(-9) dictates taking the opposite of the negative integer −9-9, which calculates directly to the positive integer 99. The notation ∣−9∣|-9| determines the geometric distance from zero for the number −9-9, which is also exactly 99. Since both evaluated outcomes are identical (9=99 = 9), it can be concluded that −(−9)=∣−9∣-(-9) = |-9|.
