is the set of integers greater than or equal to −7 and less than or equal to −1
There are 80 such integers.
The same way you can tell with integers.

No, the sum of two integers is not equal to the difference of the same two integers, except in specific cases. For two integers ( a ) and ( b ), the sum is ( a + b ) and the difference is ( a - b ). These two expressions can only be equal if one of the integers is zero or if they are equal (i.e., ( a = b )). In general, the sum will be greater than or less than the difference, depending on the values of ( a ) and ( b ).
Seven of them.
You can use the Not function or the <> operator, which is the < and the > beside each other. To see if the values in A1 and A2 are not equal to each other, you can type: =A1<>A2 or =Not(A1=A2) In each case they will either give you TRUE if they are not equal or FALSE if they are equal, in the cell that you enter the formula into.
-7 to -1 : there are 7 there. +1 to +7: there are 7 there. Then there is 0. Total 15
This is the 'null' or 'empty' set.There are no numbers greater than '-3' and less than '-9'.
All of them.
No integers fit those criteria.
They are the negative integers.
