Subject: Min max program

I've just started using ruby for a programming/math class I'm doing at
school. Was asked to write a program that finds sum min max and avge of
a random set of numbers. Have managed to write that program but it is
overly complicated. What I was wondering is if I can store this

if
  max < num1
  max = num1
end

if
   num1 < min
  min = num1
end
(repeated 8 times)

code into something that's run once but read the variables from an array
so I don't have to keep typing it and adding it in if I feel like adding
more numbers.
If I haven't explained myself that well I'll clarify if you need it.

Thanks


Here's the full code

num1 = rand(10000)
num2 = rand(10000)
num3 = rand(10000)
num4 = rand(10000)
num5 = rand(10000)
num6 = rand(10000)
num7 = rand(10000)
num8 = rand(10000)
max = 0
min = 10001

puts num1
puts num2
puts num3
puts num4
puts num5
puts num6
puts num7
puts num8

if
  max < num1
  max = num1
end
if
  max < num2
  max = num2
end
if
  max < num3
  max = num3
end
if
  max < num4
  max = num4
end
if
  max < num5
  max = num5
end
if
  max < num6
  max = num6
end
if
  max < num7
  max = num7
end
if
  max < num8
  max = num8
end

if
   num1 < min
  min = num1
end
if
  num2 < min
  min = num2
end
if
  num3 < min
  min = num3
end
if
  num4 < min
  min = num4
end
if
   num5 < min
  min = num5
end
if
  num6 < min
  min = num6
end
if
  num7 < min
  min = num7
end
if
  num8 < min
  min = num8
end
sum = num1 + num2 + num3 + num4 + num5 + num6 + num7 + num8
avge = sum / 8s
puts
puts 'sum = ' + sum.to_s + '.'
puts
puts 'max = ' + max.to_s + '.'
puts
puts 'min = ' + min.to_s + '.'
puts
puts 'Average = ' + avge.to_s + '.'
puts
$end
