Question about Texas Instruments TI-30X-IISTK Scientific Calculator
Actually, you're negating a square, not squaring a negative. When you put in -x^2, it's getting calculated as -(x^2). In order to square a negative number, use parentheses and calculate it as (-x)^2.
Also, make sure you're using the +- key to the right of th decimal point instead of the - key when entering the negative number.
