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.
-4
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
All of them.
This is the 'null' or 'empty' set.There are no numbers greater than '-3' and less than '-9'.
No integers fit those criteria.
Less than Less than or equal to Equal to Greater than Greater than or equal to
They are the negative integers.
Yes, but greater than all negative integers
