multiplication table exer. this version formats the numbers correctly using some fancy formatting stuff I found on google.

multiplicationTable.rb

puts "Exersize: 1"
#Write a program that prints out the answers of a 9 x 9 multiplication table
for x in (1..9)
  for y in (1..9)
		answer = x * y
		print "%-3d  " % answer
	end
	puts
end

puts
puts "Exersize: 2"
#Write a program that finds the largest power of 3 less than 10,000
num = 3
answer = 0
while num < 10_000
	answer = num
	num = num * 3
end
puts "#{answer} is the highest power of 3 less than 10,000"
