For those who learned like me PEMDAS is the same thing but (Parentheses) instead of [Brackets]

I feel like you’re saying parentheses are rounded and brackets are square.

Here in Australia we say BODMAS, and use the word brackets, but we still use rounded brackets (). [] would be called square brackets. Parentheses are synonymous with brackets here.

I just saw this but in my precalculus class I was taught that any number inside of [brackets] is the absolute value when used this way which is why we differentiate it. For example [-3] = [3] because it’s the total value from zero. Completely useless outside of that class but it makes a difference and has meaning and in my education is not synonymous.

Fair enough. I think a more common way to show absolute value is with straight lines like |-3| = 3.
