👉 In mathematics, a "crosiered" number is defined as a number that can be written in the form of $a^2 + b^2$ where $a$ and $b$ are integers. This means that it's also an integer square (since squaring any integer gives another integer). These numbers play a crucial role in various mathematical structures, particularly in the theory of quadratic forms and number fields. For example, consider the number 100, which can be
