How do you get a random value between positive value and negative value?
2 answers
local rng = Random.new(tick()) -- generate a new random number generator
local randomNumber
-- if you want only integers (i.e. 1, 2, 3, -1, -2, -3, etc) then
randomNumber = rng:NextInteger(-10, 10)
-- if you want real numbers (i.e. 1.5, 3.14, 2.16112231, etc) then
randomNumber = rng:NextNumber(-10, 10)
Hope this helps! :)
To simplify this you can do:
local a = math.random(-10, 10)
print(a)
finding random numbers can be used in multible different ways here

Actually math.random runs a different algorithm than the Random instance and can cause weird behavior such as: https://devforum.roblox.com/t/math-random-returns-same-number-every-time-after-a-delay-from-setting-randomseed/25243/14?u=zeuxcg . I submitted my answer using Random instead of math.random because simply put, it is better.
