its supposed to add random numbers to its position instead its an error?

workspace:WaitForChild("defaultkid99")
repeat 
    script.Parent.Position = script.Parent.Position+Vector3.new(math.random,math.random,math.random)
until script.Parent.Position = defaultkid99.Torso.Position

it tells me expected identifier when parsing epression instead got =

alright so i have a new script

workspace:WaitForChild("defaultkid99")
repeat 
	script.Parent.Position = script.Parent.Position+Vector3.new(math.random(-5,5),math.random(-5,5),math.random(-5,5))
until script.Parent.Position == defaultkid99.UpperTorso.Position

but it still doesnt work but gives me a different error

as i know you need to add 2 numbers in math.random so it will be math.random({minimum number}, {maximum number})
