これは式の足し方の順序によって答えが異なります。そのまま計算するのが正式です。200－1＋199は398です。でも、199＋1を先にして200を引くと0になってしまいます。この答えは❌です

How I got 398 1. Always start on left so 200-1=199 2. Then we add up two 199s like multiple or additional 199•2=398 or like this 199+199=398 MISTAKES YOU HAVE DONE! Never start with right as it gives you wrong answer like 200-1+199=0 because it won’t make sense and you might fail if you do smth wrong. And don’t start an argument about the wrong answer before you think carefully before saying.
