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
