Hey there!
[tex]200+204-100*3+1[/tex]
Let's start from multiplication because you have to use the order of operations(PEMDAS).
[tex]100*3=300[/tex]
Now move on to addition.
[tex]300+1=301[/tex]
Now add 200+204.
[tex]200+204=404[/tex]
Now we have to subtract it with the other side.
[tex]404-301-105\\105(ANSWER)[/tex]
Hope this helps!
