# The Challenge

You must create a program that does addition using string manipulation, similar to:

 999
+  1
----
1000


Which means the maximum amount of addition possible is 9+9+9. And your code should handle numbers up to infinity (since the addition is done on strings).

# Breakdown of 999+1

Step 1:

9+1+0=10, result=0, carry=1, output=0.


Step 2:

9+0+1=10, result=0, carry=1, output=00.


Step 3:

9+0+1=10, result=0, carry=1, output=000.


Step 4:

0+0+1=1, result=1, carry=0, output=1000.
Final output=1000


If your code does this, you did it correctly.

# Rules

• Standard code golf, least amount of characters wins.

• Nothing silly, your code must work with all addition problems, and no "In my language "a" does just this!".

• Proper loopholes (those that aren't ridiculous) apply.

### This is different from "Adding Two Numbers" because...

You must use string manipulation and must add the numbers character by character, there are restrictions past "1+1", you must do "last char of 187+last char of 988".

• I'm sorry, but this challenge makes too many assumptions about language features. What's "String manipulation"? See X without Y – Nathan Merrill Nov 14 '16 at 19:10
• String manipulation in the sense of getting characters x through y, many languages have that feature, maybe not golfing languages, but code golf doesn't have to have golfing answers. – ender_scythe Nov 14 '16 at 19:29
