timestable.rb

# Andrews' CODE
def times_table(rows)    # <-- defines method and how many rows passed as argument
  1.upto(rows) do |x|    # <-- You start first loop with value x
    line = ""
    1.upto(rows) do |y|  # <-- begin 2nd (nested) loop with value y
      line += "#{x*y}\t" #  <-- x=1 therefore 1*1, 1*2, 1*3. When done x=2 2*1, 2*2, 2*3.... (x=3, 3*1, 3*2, 3*3...)
    end
  puts line
  end                    #  <-- incremement to the next x value
end

# The basics are, that you will increment an 'x' value and then run the entire 'y' loop. 
# Then you increase 'x' and then run the whole 'y' loop again. 
# An alternative looping system could be written without the 'line' variable:

1.upto(rows) do |x|
  1.upto(rows) do |y|
    print "#{ x * y }\t"
  end
  puts
end

# Take note of why the 'puts' is placed after the 'y' loop. 
# That's to give a line break after each row of values has been printed.

Interesting. Your way is definitely better. Thanks for clearing that up. My line spacing was redundant with the \t.
