Understanding Natalie's Hat Problem

Natalie buys five hats, but half of her total hats are lost during a move, leaving her with 21 hats. To find out how many hats she originally had, we solve the equation by doubling the remaining hats to account for the loss, resulting in 42 hats before the loss. Subtracting the five she bought, Natalie originally had 37 hats.
