Grabe that is what we call: Shogy Commutative Law Theorem of Addition where we can denote that in in every addition the formula is a+b+10=b+a+10. Here is the evidence of this theorem that proves this law is correct:
150+20+10=20+150+10
170+10=170+10
180=180
Therefore this is correct.
(Sorry po. Joke lang po ito)-For fun only.
BTW thanks for sharing bro.
