is the set of integers greater than or equal to −7 and less than or equal to −1 =B−26, 24, 29
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.
