    I learned negative as being a separate operation where we need to apply the order of operations. I think it was something like : -2 is a diminutive for -1x2 so it uses the order of operations of a multiplication.
    My calculator is the official one used in schools in France (ti-83 premium ce) and it says -2^2 = -4 with the negative key. I don’t think it would make a mistake in such a simple concept.

    But whatever these concepts can change depending on the field, country, level of education. What I mean is : it’s unclear, so use parentheses. So (-2)^2 or -(2^2) are the correct ways to write it.











  • I didn’t even have an account when I lived in France because only old people used it, and I didn’t understand the billions users figures either.

    But since I live in canada I need facebook to do anything, everyone uses it. If I want to get in a bar, they ask me for my Facebook to check my age. When I get a package I only get notified on Facebook. News by my school are only published on Facebook…
