Don't use "program" or "function"
Make $2 + 2 = 5$
  • In this challenge, make a program that adds 2 integers, preferably on a function, and if the statement is `2 + 2`, return or print `5`. Shortest program in each language wins!
  • # Example ungolfed program in [Python 3.x]
  • <!-- language-all: lang-python -->
  • <pre><code>def add(x, y):
  • &#9;if x == 2 and y == 2:
  • &#9;&#9;return 5
  • &#9;else:
  • &#9;&#9;return x + y
