+# Week 18 challenge
+
+![Vegeta with scouter](image.jpg)
+
+You've been tasked to help Vegeta read data from his scouter. Unfortunately he can't read digits because of the shitty free font used by the developers. Please write a script that accepts a number as input and gives back the number as text.
+
+Examples:
+```
+getSaiyanLevel(0); // zero
+getSaiyanLevel(10); // ten
+getSaiyanLevel(30); // thirty
+getSaiyanLevel(5000); // five thousand
+getSaiyanLevel(1234); // one thousand two hundred and thirty four
+```
+
+Since Vegeta doesn't comprehend levels beyond 9000 just let him know:
+
+```
+getSaiyanLevel(9001); // it's over 9000!
+```
