Finding the square root when the player messages a number

[ASTROCPF (Astronaught)]

Code:

game.Players.PlayerAdded:Connect(function (player)
player.Chatted:Connect(function(msg)
		if msg == "find the square root of " -- this is where it checks what the number is, but I dont know what to do.
		
	end)
end)

Then, I want to connect it to a variable like this:

game.Players.PlayerAdded:Connect(function (player)
player.Chatted:Connect(function(msg)
		if msg == "find the square root of " then
		local number = --the number the player says
	end)
end)

[anon_j1124 (A47)]

local num = tonumber(string.match(msg, "%d+"))
local root = math.sqrt(num)

[ASTROCPF (Astronaught)]

like this?

game.Players.PlayerAdded:Connect(function (player)
	player.Chatted:Connect(function(msg)
		if msg == "find the square root of " then
			local num = tonumber(string.match(msg, "%d+"))
			local root = math.sqrt(num)
			print(root)
			end
		end)
end)

this doesn’t work

Try this :

game.Players.PlayerAdded:Connect(function (player)
	player.Chatted:Connect(function(msg)
		if string.match(msg:lower(), "find the square root of ") then
			local num = tonumber(string.match(msg, "%d+"))
			local root = math.sqrt(num)
			print(root)
			end
		end)
end)

Not like that.

player.Chatted:Connect(function(msg)
    if string.match(string.lower(msg), "find the square root of ") then
        -- my code here
    end
end)

@Minhseu123 and @anon_j1124 thanks for the help. But I have another problem, I dont know how to do equations like 2 + 1 or 3 x 2,

elseif string.match(msg:lower(), "find the sum of (number) and (number)") then

I want it to find the sum of two numbers then add the numbers and print it out.

This should help.
