Change series of numbers from positive to negative

[Wyatt Murphy]

I have a series of postive numbers. All I want to do is change them to
negative. They are all independent from each other and different.
Thanks!

In an unused cell enter -1 and copy it.
Select the cells you want to change and
paste/special with the multiply button checked

In blank cell enter -1, select it, copy, select range of cells with
positive numbers, go to Edit -> Paste special -> in Paste Special
dialog select Values and Multiply.
