Yes, you do have the division key. It is the division key. However, if you want the fraction to remain a fraction, enter the numerator, press the division key, type in the denominator then Press [MATH] [1:>Frac] then press ENTER. The fraction that will be displayed will be the reduced form.

Bien que je n'appr?cie pas de lire un texte en charabia, je vais essayer de r?pondre ? ta question.
Si tu as une touche MATH, appuie dessus. Tu devrais voir alors une liste de commandes parmi lesquelles figure une t?te de fl?che ?paisse devant FRAC. Saisis ta fraction, appuie sur MATH puis s?lectionne la commande >Frac. Appuie sur ENTER. Le r?sultat sera LA fraction r?duite ?quivalente.
Si tu veux convertir une fraction en sa repr?sentation d?cimale fais la m?me chose que ci-dessus mais s?lectionne >DEC.

No. The calculator runs on the four AAA batteries. The lithium battery is solely to retain the contents of the memory while you change the AAA batteries. If you don't care about retaining the memory, you don't need the lithium battery. You do, however, need the AAA batteries to use the calculator.

It could. If the x range doesn't include x=0 then the y axis will not show. Likewise, if the y range doesn't include y=0 then the x axis will not show.

It sounds like the contrast is set wrong for the calculator. Try pressing 2nd down multiple times until you get the color you want.

It's the fifth item on the MATH menu.

As an example, to calculate 7!, press 7 MATH 5 ENTER.

1 . 0 7 ^ 3 0 ENTER

^ is the key just above the divide key.

This functionality is not available in the TI-82, it was added in the TI-83.

There is no percentage button. To turn your answer into a percentage, simply divide by 100. To find, for example, 64% of 200, type in .64*100.

Turn the calculator on. Press and release the 2ND key, then press and hold the up-arrow key until the screen darkens to your taste. If you go too far, use the 2ND and down-arrow keys to lighten the screen.

The arrow is the STO key just to the left of the 1 key. The comma key is just above the 7 key.

The slope is the coefficient of the x term and the intercept is the constant term. So, for f(x)=-8x-6, the slope is -8 and the intercept is -6.

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

Having gone over a month with no response, I assume it was just a contrast problem, solved by my suggestion.

Having received no response in over a month, I assume it was just a contrast problem.

Press and release the 2ND key. Press and hold the up-arrow key to increase contrast or the down-arrow key to decrease the contrast.

Press and release the 2ND key. Press and hold the up-arrow key for a few seconds. If you go too far, repeat the process using the 2ND and down-arrow keys.

Having received no response in over a month, I assume this is no longer a problem.

The easiest solution would be to move the variable to only one side. This is not that difficult. For example your given equation is 8(3x-5)-4=4x-10; subtracting both sides of this equation by 4x would give 8(3x-5)-4-4x=10.
