Multiply the number by -1 to reverse its sign:

A1: -10

=A1*-1 returns 10

A1: 10

=A1*-1 returns -10

Try this:

=MIN(A1,-A1)

This will keep negative numbers and turn positive numbers to negative.

Hope this helps.

Try these.
1. When entering the number, put a minus sign in front of it.
2. If your positivie number is in cell A1, enter =-a1 in, say cell b1.
3. If you have a group of mixed numbers (positive and negative), use an IF
statement in cell b1. E.g. =if(a1=0,a1,-a1) and copy.

If your postitive number is in A1, =-A1 will give you the negative number.
Otherwise you put -1 in a spare cell, Copy, then select the cell(s)
containing your positive number(s), and Edit/ Paste Special/ Multiply (or
Divide).

The simple thing to remember is that Excel uses a hyphen as a minus sign.

Thanks...but I was hoping to find a faster way to switch a range.
