Puzzle #1: Cryptarithmetic

In a cryptarithmetic puzzle you must find a digit that represents each letter in the puzzle to make the equation true.  A specific digit can substitute for only one letter (i.e., all letters must have a different digit) and zero cannot be used for a letter appearing on the far left.

For example:

  I
+AM
===
BOB

One possible solution would be I=8, A=9, M=3, B=1, and O=0:

  8
+93
===
101

You are asked to solve the following equation:

   TEN
   TEN
  NINE
 EIGHT
+THREE
======
 FORTY

Please find a value for each letter.  You may use any method you wish (writing a program, by hand, whatever!)

Please submit the correct answer by March 1st, 2016.  One $10 gift card will be awarded randomly from those who submitted the correct answer.

Thank you to everyone who submitted an answer (a lot of correct answers were submitted!) but sadly, there can only be one winner.  The winner is: Pooja Ahuja.
