I had a little trouble understanding what your code is supposed to do,
but this code will keep asking you for numbers until you answer with
an empty response (just hit enter)

It shows the equations as you enter them, and then in the end gives
you a summary of the one's you've entered.  It does not account for
all possible errors.

Look up String#empty,  Array#<<, break, loop, and
Array#each_with_index to understand a bit better what's going on.

Welcome to Ruby.  You might try out http://tryruby.hobix.com as well
as get acquainted with the documentation at http://ruby-doc.org

Glad to see you hacking, newbie or not :)

firsts = []
seconds = []
answers = []
loop do
  puts 'Enter a number'
  first = gets.chomp
  break if first.empty?
  firsts << first_number = first.to_i
  puts '...good.'
  puts 'Now enter a number to multiply to the first number'
  second = gets.chomp
  break if second.empty?
  seconds << second_number = second.to_i
  answers << answer = (first_number * second_number)
  puts "#{first_number} * #{second_number} = #{answer}"
end

puts 'okay now we are going to look at all the questions your asked'
answers.each_with_index do |c,i|
  puts "#{firsts[i]} * #{seconds[i]} = #{c}"
end
