# Intro

I joked with my friend Dustin about creating solutions to the Project Euler problems using LUA (and running them in WoW). Here's where I'll post those solutions as I finish them.

I'll try to generalize my solutions where I see fit. For example, I added a parameter to Problem 1 to set the upper limit of 1000, but I did not parameterize the 3 and 5, etc.

# Problem 1

```function ProjectEuler:OnEnable()
ProjectEuler:Problem001(1000)
end
function ProjectEuler:Problem001(upperLimit)
self:Print("Sum of all numbers less than "
.. upperLimit .. " that are divisible by 3 or 5")

local f = function(factor)
local n = math.ceil(upperLimit / factor)
return n * (n-1) * factor / 2
end

local result = f(3) + f(5) - f(15)

self:Print(result)
end```

# Problem 2

```function ProjectEuler:Problem002(upperLimit)
self:Print("Sum of all even numbers less than " .. upperLimit .. " in Fibonacci Sequence")

local result, x1, x2 = 0, 1, 2

local f = function(t1, t2)
return t2, t1+t2
end

while x2 < upperLimit
do
