As we know,

1-1=0

let,

a = 1 , b = 1

then,

a - b = 0

also,

a^2 - b^2 = 0 as a^2 = 1 and b^2 = 1

thus as per algebra

(a - b)(a + b) = 0

thus,

i.e, a - b = 0 and a + b = 0

i.e, 1 - 1 = 0 and 2 = 0.

This isn't really new: hide zero in a variable and divide by it. What's new is, that you have hidden the division in a multiplication as you used a false logical statement: AND instead of OR. And even OR isn't necessarily true.

I'm not very comfortable with this kind of "joke" because it is simply just wrong on so many levels, that these examples guide the wrong way to seriously learn mathematics. There are better "jokes" where you can actually learn something instead of to learn how to make mistakes. I've seen the above on so many occasions in students' homework or tests, that it is not funny at all. We try to improve mathematical skills, not to damage them.

Doesn't really work as a joke because, as already pointed out you made a mistake, it's OR not AND.

I get that but just did that for pun man I am not at all serious about it.

How about this one,

I use this as magic trick to amuse my nephew

I think of any number between 20000 and 30000

say 29547 then I put in an envelop

then

I give a number 9549

then I ask for a random number from my nephew suppose he says 2347

then I say a random number 7652

then I ask for another random number and he says 4587

then I say a random number 5412

then I tell him to add it all up vol-ah you get 29547.

What trick have I used and can you do it for number range 50000 to 60000

Yours are non-computable whereas mine are tearable if listed on a piece of paper with small tearable strips for each joke.

Here's some general purpose tearable jokes:
