Add two numbers

Question

Input: Two integers. Preferably decimal integers, but other forms of numbers can be used. These can be given to the code in standard input, as arguments to the program or function, or as a list.

Output: Their sum. Use the same format for output integers as input integers. For example, the input 5 16 would lead to the output 21.

Restrictions: No standard loopholes please. This is code-golf, answer in lowest amount of bytes wins.

Notes: This should be fairly trivial, however I'm interested to see how it can be implemented. The answer can be a complete program or a function, but please identify which one it is.

Test cases:

1 2 -> 3
14 15 -> 29
7 9 -> 16
-1 8 -> 7
8 -9 -> -1
-8 -9 -> -17

Or as CSV:

a,b,c
1,2,3
14,15,29
7,9,16
-1,8,7
8,-9,-1
-8,-9,-17

• Dennis: This is quite trivial, but not really simpler than, e.g., the Hello World catalog. Given that the ability to add integers is one of our two requirements for programming languages, I'd say it's worthwhile to have if properly specified.
• FinW: Can the answer take input with preceding zeros as default? e.g. 5 16 is inputted as 005 016
• anna328p: @FinW Sure. As long as they don't get interpreted as octal.

Explanation

( #Input a decimal integer and store it into the cell at the pointer#
@ #Rewrite the value of the register with the cell at the pointer#
( #Input a decimal integer and store it into the cell at the pointer#
+ #Add the register by the cell at the pointer, now the register contains the sum#
% #Rewrite the cell at the pointer with the value of the register#
) #Output the cell as the pointer (the sum) as decimal integer#

a

Pretty simple, a is the built-in addition function in SqueezeL.

Answer 3

CALKOWITE:I
SUM(I,1,W(I))

Takes input as a list of size 2 under the name of W.
This is a solution by using a builtin. I included the variable declaration, as it must use an integer variable, but this isn't supposed to be a full programme.
