My daughter is struggling with this problem: on TI-84s, "(-) 3 x^2 Enter" gives -9. Personally, I think that if you have a dedicated negation operator it should have a higher precedence than power, but at the very least the calculator could highlight what it's doing.
"Hypercalc" the Android app does it, but TI-84 is the standard..

- Georgelemental 4y ago> a dedicated negation operator it should have a higher precedence than power I prefer the traditional precedence; it ensures - 3 ^ 2 = 0 - 3 ^ 2
- jhallenworld 4y agoI understand the argument, I just wish that the most standard school calculator would highlight somehow what it's doing Another one is "2 ^ 1 / 2 Enter". Some calculators give 1, newer ones give sqrt(2).
- weberer 4y agoI'm not sure what the parenthesis around the negative sign is supposed to accomplish. Generally you put it around two or more operators.
- jhallenworld 4y agoIt's how the key is labeled.
