Hey,
for the math, this should be a fairly easy one with functions:

Spoiler


local result = 0
local numberone = 0
local numbertwo = 0
function getnumberone()
numberone = read()
end
function getnumbertwo()
numbertwo = read()
end
function addition()
result = numberone + numbertwo
end
function printresult()
print(numberone .. " + " .. numbertwo .. " = " result)
end
getnumberone()
getnumbertwo()
addition()
printresult()

However you can do it smaller without functions:


local result = 0
local numberone = 0
local numbertwo = 0
numberone = read()
numbertwo = read()
result = numberone + numbertwo
print(numberone .. " + " .. numbertwo .. " = " result)

This should be the smallest one:


print(read() + read())

edit:
For the refueling i would recommand a function similar to this one:

Spoiler


local function checkFuel()
if turtle.getFuelLevel() < 1 then
  turtle.select(1)
  turtle.refuel(1)
  print("Refueled!")
end
end

But you would have to add it after every turtle.forward() ect. so it is kinda bad.
So you may use something like this:

Spoiler


local function checkFuel()
if turtle.getFuelLevel() < 1 then
  turtle.select(1)
  turtle.refuel(1)
  print("Refueled!")
end
end
local function forward(j)
for i=1,j,1 do
  turtle.forward()
  checkFuel()
end
end
--If you want the Turle to move one block forward
forward(1)
--If you want the turtle to  move 5 blocks forward
forward(5)

Simply do this for turtle.up() and turtle.down() and turtle.back() if you need them.

Spoiler


local function back(j)
for i=1,j,1 do
  turtle.back()
  checkFuel()
end
end
local function up(j)
for i=1,j,1 do
  turtle.up()
  checkFuel()
end
end
local function down(j)
for i=1,j,1 do
  turtle.down()
  checkFuel()
end
end
