Change a negative sign to positive

[Mjkqb]

What is the best way to change a negative number with a minus sign to display with a plus sign.
I don't want to affect any positive numbers, only negative.
-1 should display as +1.
1 should display as 1.

Below is the formula I'm using.
=MIN(ROUND(MIN(B10,18)*112/113+63.3-70,0),18)

Can this formula be modified to include the minus/plus change?

Please let me know if you need more info.
Thanks

If i understand you can use:

=A1*SIGN(A1)

This will produce positives as they were and negatives will become positive. That what you meant?

ABS(A1)
Returns the absolute value of a number. The absolute value of a number is the number without its sign.

so +ve numbers stay positive and -ve numbers become positive

Do you only want to change the displayed value, or alter the actual value?

Only the displayed value.
If it is a negative number it needs to be displayed as a positive number with a plus sign.
The other positive numbers should be absolute with no sign.
Including a screen shot.
You can see there are only a couple of cells with a -1 value, but they must be displayed as +1

All you should need is a custom number format like:
0;”+”0

Thanks so much. That worked perfectly. Pretty new at this, just curious about the quotation marks. I had to remove them as they were being displayed.
