Formula to return a inverse of a number

[SALO]

Does anyone know how to have a formula in cell AH71 that will reference a number in a cell AH70 and just return the inverse of the number. For example if AH70 is a negative -550,000 to just return the value 550,000. There are a number of ways to do this but is there just a simple Inverse formula?

How about =-AH70?

or you could do is AH71= AH70, and select CTRL +1 on the number tab select custom and just type the below intoo the text box

0;0
