1) What is the difference between puts and print?

2) For big numbers (thousands, millions, billions etc) what is an alternative syntax that ruby provides? Provide an example.

3) What do these methods do? to_s, to_i, puts, gets, chomp

4) What is the programming term when you place a variable inside a string like so: "Author is #{author_age_in_years} years old."

Extra Credit: Explain why in Ruby you can use the "+" operator to add numbers and build strings?

puts "2) For big numbers (thousands, millions, billions etc) what is an alternative syntax that ruby provides?"

# My Head says:
# Ruby has a nice feature to write big numbers. It can make them more visible by using _
# for example :

puts "100_11_1111_223 + 1_122_314_321_231_323 = " + (100_11_1111_223 + 1_122_314_321_231_323).to_s

# 3) What do these methods do? to_s, to_i, puts, gets, chomp
puts "3) What do these methods do? to_s, to_i, puts, gets, chomp:"


# to_s converts to string. Like my previous example:
puts "100_11_1111_223 + 1_122_314_321_231_323 = " + (100_11_1111_223 + 1_122_314_321_231_323).to_s

# to_i converts to integer. Like my new example:
some_stuupid_string1 = "100_11_1111_223"
some_stuupid_string2 = "1_122_314_321_231_323"
puts some_stuupid_string1.to_i + some_stuupid_string2.to_i

# puts and gets write and read strings with new lines too
some_stuupid_string3 = gets  # i read some s### here :)
puts some_stuupid_string3 + some_stuupid_string3 # i write that same s### 2 times out in 2 lines
puts some_stuupid_string3.chomp + some_stuupid_string3.chomp# but now i write that same s#### without itzs final END LINE so it writes in the same line twice
