How to generate negative random numbers

[scifer 10]

I'd like to generate a random number ranging from -10 to +10. How to do that?

(random 20) - 10 ????

How about (random 10) - 20 :)

[.kju 3245]

random 10 = 0 - 10

0 - 10 minus 20 = -20 to -10

(random 10) * -1

(random 10) * -1

Genius!

random 10 = 0 - 10

0 - 10 minus 20 = -20 to -10

Yes, but you wrote "random (20) - 10", which is -10 to 10.
