>>10855923hahaha mate you just absolutely butchered the expression.
The expression is "8/2(2+2)" and 2(2+2) is not by itselft, nor a function, nor directly algebra. It is apart of the expression 8/2(2+2) it makes semse logically that it becomes read left to right the moment we set it as 8/2(4) or 8/2*4.
This convention makes sense seeing as () is just for enabling the plus action to happen first in the expression.
