attempt to compare number < boolean?

so i tried making a script that detects when the player's health decreases, but i kept getting "attempt to compare number < boolean". i'm pretty sure the boolean value is "newHealth", but how can that be a boolean value? here's the code (it's a local script, in StarterCharacterScripts)

local char = script.Parent
local hum = char:FindFirstChild("Humanoid")
local oldHealth = hum.Health

hum.HealthChanged:Connect(function(newHealth)

	if math.abs(oldHealth - newHealth) <= 10 > 1 then
		--code
	end
end)

thanks in advance

Nevermind, I had to change the if statement to this

if math.abs(oldHealth - hum.Health) <= 10 and math.abs(oldHealth - hum.Health) > 1 then
	--code
end

What XD_Destroyer1234 meant:

local char = script.Parent
local hum = char:FindFirstChild("Humanoid")
local oldHealth = hum.Health

if math.abs(oldHealth - hum.Health) <= 10 and math.abs(oldHealth - hum.Health) > 1 then
    --code
end
