{Lessons} Lesson Number Five: Gratis Calculator!

Did you happen to know that Ruby has a free calculator? It can't do very complicated stuff, but it can do basic stuff, like addition and multiplication.


Addition
Just do a+b. To show the result, write a line like below:
print "19325325+123123247 is ",  19325325+123123247, ".\n" 
Subtraction
Just do a-b. To show the result, write a line like below:
print "19325325-123123247 is ",  19325325-123123247, ".\n" 
Multiplication
Just do a*b. To show the result, write a line like below:
print "19325325*123123247 is ",  19325325*123123247, ".\n" 
Division
Just do a/b. To show the result, write a line like below:
print "19325325/123123247 is ",  19325325/123123247, ".\n" 
Division with Remainder(Useful)
Just do a%b. To show the result, write a line like below: (Weird)
print "19325325%123123247 is ",  19325325%123123247, ".\n"
(You may want to change % to something like x divided by y is z.) 
XSquared
Just do a**b. To show the result, write a line like above:
print "19325325**123123247 is ",  19325325**123123247, ".\n" 
(You may not want to do this with such a big number)
P.S: Mind the space after the is or it will show up scrunched up.
