Minus and change-sign are two completely different things. Minus is used to subtract one number from another. When you press minus when the input line is empty, your telling the calculator to subtract. The only way it can subtract the number you're about to put in is to subtract it from something else, and that something else is the previous answer, hence the "Ans."If you want to input a negative number, use the change-sign key. If you want to subtract one number from another number, use the minus key.Try pressing the plus key when the input line is empty. You'll get Ans+ in this case as well, The same with multiply and divide, among others, and for the same reason.

### How can you program games

Do not even go there. The calculator is pretty basic and does not have memory to store instructions. If you want to take up programming ( a worthwhile endeavor) buy a graphing calculator such as a TI 89 itanium, a TI Voyage 200PLT, a TINspire, or a Casio Graphing calculator FX 9860 SD, ClassPad 330, or some top of the line HP calculators (HP 49G+, HP 50 G).

### Texas Instruments TI-5045 SV paper won't advance

The foam on the feed roller is probably decayed/ soft. Which has caused the plastic gear that engages that drive gear to wear. If the gear is moved/ spaced over to pick up the 40% that isn't trashed - it'll feed.

I'm going to try to fix my Goodwill purchase anyway. Anything is better that the Canon piece of rubbish I have now. Mybe someone can tell Canon that a few months of use is not enough?

### Why is my ti84 giving me wrong answers when I use trig functions?

Your right you should be in degree mode. However, my guess is you are somehow entering in cot wrong in your calc. Recall cot = 1/tan! In your graphing calculator enter: 35(1/tan(61) = 19.4. Hope this helped!

The simplest way would be to create a table where each x-value has a y-value that is the residual at the corresponding x. With a 2-list data set you can plot you residual plot.

### My TI BA II Plus is returning incorrect answers for TVM problems... Is this common and can it be fixed?

Let's see, 10% interest per year on \$100 for one month. That's 10/12 of a percent interest on \$100 is \$0.83, added to \$100 is \$100.83 (with a bunch more 3s at the end). Clearly this is the correct answer. What answer are you expecting? The future value at the end of one year instead of one month?
