Most of my pages lack this, but this is a lot of work on my side, so...

Thank you.
Instead of numbers, let us look at something different.
Boolean values.
If you happen to know how to program, then you nearly must have known this concept, although possibly not knowingly such.
There are lots of numbers, but there are only two boolean values: true (sometimes written as 1) and false (sometimes written as 0). Note that capitalization differs in multiple languages. For instance, Python uses titled strings like True and False. Note that the word bools is the same as the phrase boolean values. This is for simplicity (and laziness).
Now that you have the values, let us look at the calculation symbols.
The = sign, of course, is still used in boolean arithmetic.
Little side note:
Programming languages use == for checking equality to differentiate from declaring variables. This is just for you to note for you are going to see program examples. No worries, you do not need to have programming basics. Also, != is used for ≠, <= for ≤, >= for ≥.
