setTimer(function()

x1 = math.random(500)

x2 = math.random(600)

outputChatBox("#1860F1[Math]#ffffff " .. x1 .. " + " .. x2 .. " = ", root, 255, 255, 255, true)

end, 30000, 0)

 

function mathSystem(text, source)

outputChatBox(text, source, 255, 255, 255, true)

if text == x1 + x2 then

givePlayerMoney(source, 2000)

end

end

addEventHandler("onPlayerChat", root, mathSystem)

1. setTimer(function()
2. x1 = math.random(1,1000)
3. x2 = math.random(1,1000)
4. outputChatBox("#1860F1[Math]#ffffff " .. x1 .. " + " .. x2 .. " = ", root, 255, 255, 255, true)
5. end, 30000, 0)
6. function mathSystem(text, source)
7. outputChatBox(text, source, 255, 255, 255, true)
8. if text == x1 + x2 then
9. givePlayerMoney(source, 2000)
10. end
11. end

    That's the error math.random need to be for example (1,500) from 1 to 500

try this 

local result = nil 

setTimer(function()
local x1,x2 = math.random(1,1000) , math.random(1,1000)
result = x1 + x2
outputChatBox("#1860F1[Math]#ffffff " .. x1 .. " + " .. x2 .. " = ", root, 255, 255, 255, true)
end, 30000, 0)

addEventHandler ( "onPlayerChat" , root , function ( message , typ ) 
if ( typ == 0 and result ~= nil and message == tostring ( result ) ) then 
givePlayerMoney ( source , 2000 ) 
result = nil 
end
end )
