Sorry i dont see where, bob wrote that =|.
ok i understand everyones ways of going about this except bobs ways of 
using parameters and returned values is messing me up a bit. So heres my 
finished product, if anyone sees anything usless or somthing im doing 
wrong, please let me know :)

puts 'How many problems do you want to solve?'
problems = gets.chomp

5.downto(1) do |x|
  puts "The test will beging #{x} in seconds! "
  sleep 1
end
puts 'Start!'
def correct=(correct)
    @correct = correct
    end

  def correct
   @correct
   end
@correct = 0
 def multiply
multiple2 = rand(11)
multiple1 = rand(11)
  answer = multiple1 * multiple2
puts 'what is ' + multiple1.to_s + ' * ' + multiple2.to_s + ' ?'
  answerp = gets.chomp
  if answer.to_s == answerp.to_s
    puts "good job"
    @correct = @correct + 1
  else puts "You fail!"
  end
end

problems.to_i.times do multiply
end

puts correct.to_i
