(-9) + (-11) is greater than (-9) - (-11)
Solution:
The requirement of the above question is to check (-9) + (-11) is greater than (-9) - (-11).
There are two given expressions: (-9) + (-11) and (-9) - (-11).
Now let us put the integer rules to identify which one is greater
On simplifying, (-9) + (-11) we get,
= (-9) + (-11)
= - 9 - 11
= - 20
Similarly, on simplifying (-9) - (-11) we get
= (-9) – (-11) = -9 + 11
= -9 + 11
= 2
Applying integer rules -20 < 2.
Therefore, -9 + (-11) < (-9) - (-11). Hence (-9) + (-11) is greater than (-9) - (-11) is a false statement.
✦ Try This: State whether the statement is true or false. (-9) (-11) is smaller than (-9) - (-11).
We can apply integer rules and the order of operations to identify whether (-9) (-11) is smaller than (-9) - (-11).

(-9) + (-11) is greater than (-9) - (-11).
Summary:
After applying the integer rules and PEMDAS, on simplifying we have -20 < 2. Therefore, -9 + (-11) < (-9) - (-11). Hence (-9) + (-11) is greater than (-9) - (-11) is a false statement
