Consider your opening comment:

This is very clearly incorrect.

Let A = 10 and B = C = D = 1.

Hostile and zero explanation.

10 - 1 + 1 = 10 - 1 - 1 or 8 = 8

You need to relearn arithmetic.

Again, hostile and zero explanation.

Elaborate

10 - 1 + 1 = 10

Again, zero explanation.

This isn’t helpful when my error was misremembering how to use the order of operations while showering. You should work on your communication skills before trying to correct my faulty math equations in the future.

This is me explaining to you that you aren’t being helpful, and should work on your communication skills because you have been hostile and unhelpful since start, while also admitting that I had made an error.

Piss off and learn 2nd grade math.

No need to be so hostile over a simple mix up bud.

You continuing to be hostile, me continuing to point it out.

Check your freaking comments in this thread.

Was I thorough enough for your liking?
