Hmm, I don't know if this will help at all, but maybe if I'm understanding this correctly...

But let's say the equation 1 + 1 = 2.  Now going to a more logical standpoint instead of mathematical.  One could maybe compare this to apples.  Say you picked 1 apple from a tree, you currently only have 1 apple.  Now, what happens when you pick another apple.  This gives you two apples.  Now when talking about math, it is moreso non-existent, the numbers are just that, numbers.  But in order to understand this concept logically, one can compare to the above example as I just gave.  Though I am not fully sure if this is what you're actually asking or not...

Please guide me how to understand the maths equation logic  ?

please give me one example with logical explanation that would help me to capture logic from equations . thanks
