So who wants to help with a maths problem Im very confused about? Its apart of the easy section but I kinda dont get it.

This is the problem:

a=0 b=-1 c=-3

√3a+2b²-c³

I do the square root last because on the equation it is over all of the numbers.
So the answer on the calculator without square rooting it is 25. but when I work it out myself I keep getting 29. This is how I worked it out my way

(3x0) + (2x-1²) - (-3³)
0 + 2 - -27
2 - -27
29 (but for some reason the calculator thinks its 25)

Here is where I get confused, because when you subtract a negative number it will turn into an addition, I even looked it up and used the calculator to work out 2-(-27) and it equaled 29. SO HOW IS IT WHEN I PUT THE WHOLE EQUATION (MINUS THE SQUARE ROOT) I GET 25. I dont get it man, maths is confusing or maybe im just overthinking it. SOmeone tell me im just making a stupid mistake or something

Trivial it is as u just need to know and implement the order of operations rubric correctly. b squared is one. c cubed is - 27. Ignore the a. Then we have 2 + 27 = 29. There it is.

@ClanNaFiacaillApWythe thank you very much! The calculator was confusing me way too much 😓

@SeductiveCactus Calculators are little computers. They have speed but no understanding. They do exactly what they are programmed to do, no more and no less. These are simple binary operations that they do that lead up to the results of base 10 arithmetic. All interpretation and ordering has to be done by the operator.
