Use the x^2 function on the g-shifted '*' key (multiplication). Press 4 g *

Alternative, just multiply 4 by 4.

How can I fix HP12c when keys do not respond?


HP lists on their site (and in user manual) a way to run a key test to see which keys are bad. I'd start there.Type "hp 12c key test" into your search window on your browser and the first thing that comes up should answer it. Took me about 4 seconds to find this.

When I square a negative number, my calculator gives me a negative number. i.e. -4^2=-16


No, you're not squaring a negative number, you're negating a square. When you press (-) 4 ^ 2 ENTER , the calculator is calculating -(4^2). 4^2 is 16, and the negative of that is -16. What you want to do is to calculate (-4)^2 by pressing ( (-) 4 ) ^ 2 ENTER .

I cant figure out how to get the square root of a negative number


The square root of a negative number is an imaginary number, and the TI-30XA does not deal with imaginary numbers.

However, the square root of -x is equal to i times the square root of x. So, to calculate the square root of -4, for example, press 4 square_root = and read 2. Thus the square root of -4 is 2i.

Find missing number in this progression: 15 26 34 51 ? 84 96 125 hh22@cox.net


The missing number is 61.
Look at perfect squares: (1,4,9),16, 25, 36, 49,64, 81,100,121
Then look at the given progression 15, 26, 34, 51, x, 84, 96,125
Take differences from the closest -1,+1, -2, +2, -3, +3, -4, +4

(15 is 1 less than 16 = 4 squared,
26 is 1 more than 25 = 5 squared,
34 is 2 less than 36 = 6 squared,
51 is 2 more than 49 = 7 squared,
61 is 3 less than 64 = 8 squared,
84 is 3 more than 81 = 9 squared,
96 is 4 less than 100 = 10 squared,
125 is 4 more than 121 = 11 squared)
