Sorry for a late response. I'll try my best to clarify here. Let's forget about anything dealing with the operator right now. Instead, let's think of regular math here.
When you write 1 = 3 and 2 = 3, you are basically writing that that number 1 is equal to number 3, and that number 2 is equal to number 3. It's as if it's saying "x = 3" and "y = 3," and it just so happens that the numbers you are given to define "x" is 1 and "y" is 2 (or in other words, you have (1, 2), which is something you would see regularly in Algebra). You are stating that that is what it is, and since there is no other functions going into it (i.e. +, -, /, *), that it is definite.
Now, with the above said, if you were to change the formula to as follows: (1 + 2) = 3, now you have set a calculation. You have a "+" symbol, meaning that whatever comes before and after it will produce the answer. So if it's (1 + 2) = 3, this is a correct answer (true). Why? Because the numbers 1
+ 2 truly do equal 3. However, if you were to write (2 + 2) = 5, this is wrong (false). Why? Because the symbol "+" is looking for the numbers before and after it to produce the correct calculation, which is 4, but it has an error because how can it equal 5? This is the cause for this being
I've used technical terms in order to get across my point. I hope this was able to clarify more and was found helpful. If it wasn't I'm sorry in advance for not getting a better concept for you.
