My simple script to make a calculator, made it in less then 7 minutes i believe:
Code:
puts 'please type add for addition, sub for subtraction, div for division, or mult for multiplication.'
# telling them that they need to do this.
command = gets.chomp
# this gets the command to tell what type of math they are doing.
if command == 'add'
puts 'please put the first number in, press enter, then put in the second number, and press enter.'
addone = gets.chomp
addtwo = gets.chomp
puts addone.to_f + addtwo.to_f
end
if command == 'sub'
puts 'please put the first number in, press enter, then put in the second number, and press enter.'
subone = gets.chomp
subtwo = gets.chomp
puts subone.to_f - subtwo.to_f
end
if command == 'div'
puts 'please put the first number in, press enter, then put in the second number, and press enter.'
divone = gets.chomp
divtwo = gets.chomp
puts divone.to_f / divtwo.to_f
end
if command == 'mult'
puts 'please put the first number in, press enter, then put in the second number, and press enter.'
multone = gets.chomp
multtwo = gets.chomp
puts multone.to_f * multtwo.to_f
end
