I'm loosing marks due to my dodgy calculating skills.

Basically I'm trying to use this
X= -2.667
On my calculator I have to use x= 0-2.667 otherwise it throws up an error

Anyway the equation is x^3 -4x^2+3

The answer should be -6.481 however if I use x as a variable I always get -44.something unless I type it in exactly as this

(0-x^3-X^2+3) AND X IS set to equal -2.667

What am I doing wrong. The calculator is a sharp else 516 I got from america

Actually ignore this question I made a mistake rushing it. Cheers
