Math - Number reverse

I'm not really sure how to reverse a number from Minus to positive in the editor. Would it work if I used the "Arithmetic" to do something like ( ( -120 - -120 ) + 120 ) ?

Yes, a double negative returns a positive.

so - - 120 = 120

And (-120 - - 120) = 0

ok ty

lol u theres an easy way.. you can mutiply by -1 for exact opposite ....for always positie you use the abs funtcion and for always neg u use abs then times -1, ....now take the integral of it and find the maclaurin series of it

|x| = positive of x
x * -1 = opposite of x
