Equation generator making multiple of same answer every time?

I'm trying to make a simple equation generator for my game. For the most part it works, but, EVERY time it makes one of the incorrect answers twice. I'm assuming this has something to do with math.random.() I'm trying to use math.random(tick()) but it still isn't fixing it.

(This isn't the entire script)

Have a look at line 45

local pos = 1
local level = script.Parent.Parent.Parent:WaitForChild("correct").Value 
local number1=math.random((level*5)*-1,level*5)
local number2=math.random((level*5)*-1,level*5)
local EquationType = math.random(1,10)
math.randomseed(tick())
if EquationType == 1 or EquationType == 2 or EquationType == 3 then
    script.Parent.question.Text = number1.." + "..number2.." ="
    if number2 < 0 then
        script.Parent.question.Text = number1.." + ("..number2..") ="
    else
        script.Parent.question.Text = number1.." + "..number2.." ="
    end
    answer = ((number1+number2))
elseif EquationType == 4 or EquationType == 5 or EquationType == 6 then
    if number2 < 0 then
        script.Parent.question.Text = number1.." - ("..number2..") ="
    else
        script.Parent.question.Text = number1.." - "..number2.." ="
    end
    answer = ((number1-number2))
elseif EquationType == 7 or EquationType == 8 or EquationType == 9 then
    if number2 < 0 then
        script.Parent.question.Text = number1.." x ("..number2..") ="
    else
        script.Parent.question.Text = number1.." x "..number2.." ="
    end
    answer = ((number1*number2))
elseif EquationType == 10 then
    if number2 < 0 then
        script.Parent.question.Text = number1.." / ("..number2..") ="
    else
        script.Parent.question.Text = number1.." / "..number2.." ="
    end
    answer = math.floor((number1)/(number2)*10)/10
end
for i,v in pairs(script.Parent:GetChildren()) do
    if v.ClassName == "TextButton" then
        v.Position = positions[pos]
        pos = pos + 1
        if v.Name == "correct" then                 
            v.Text = (answer)           
        elseif v.Name == "incorrect" then
            repeat
                print("trying to select wrong number")
                wait()
                local EquationType = math.random(1,10)
                if EquationType == 1 or EquationType == 2 or EquationType == 3 then
                    wanswer = ((number1+number2))
                elseif EquationType == 4 or EquationType == 5 or EquationType == 6 then
                    wanswer = ((number1-number2))
                elseif EquationType == 7 or EquationType == 8 or EquationType == 9 then
                    wanswer = ((number1*number2))
                elseif EquationType == 10 then
                    wanswer = math.floor((number1)/(number2)*10)/10
                end
            until wanswer ~= answer 
            v.Text = (wanswer)
        end 
    end
