Lagrange's four-square theorem states that every natural number can be represented as the sum of four integer squares (e.g.,

The most common theory points to early BBC radio broadcasts. Commentators used a numbered grid in newspapers to help listeners visualize the field; "Square One" was the area around the goal.

The popular idiom has two primary origin theories, both rooted in how we visualize space:

Another theory links it to classic games like Snakes and Ladders (or Chutes and Ladders), where a bad roll could send a player right back to the very first square on the board. 2. The Four-Square Writing Method
