Well it depends on what you are wanting to do.

1. Graphing- get a graphing calculator!
2. logistics- for log base 10, just divide the number by 10.
3. ln- divide the # by the number e (roughly 2.72)
4. sine, cosine, and tangent- there should be a "SIN", "COS", and "TAN" button, if not the ratio for each, respectivly is opposite/hypotnenuse, adjacent/hypoteneuse, and opposite/adjacent. (The opp/adj being side opp or adj of angle you are doing)

### How do i put the equation x+4y=20 on my calculator?

You cannot. The TI-30XA is a simple calculator lacking any symbolic algebra or equation processing. However, if your task is "given a value for x, what is the value for y" for the equation you give, you can rearrange it a little:

Thus, if you want to determine the value of y for x = 16, key in 5 [-] 16 [&#247;] 4 [=] and get the result y = 1. To double check, substitute x and y in the original equation:
16 + 4 x 1 = 16 + 4 = 20.

### Beginning algebra-help-

It's an algebraic calculator that evaluates higher order functions like X, / before +, -.

So you have to make sure you input properly.

1-61+2= will give you top line result.

Then enter
/
(
5-6
)
=

You need the brackets for the divisor or it will divide the top line result by 5 and then subtract 6 from that result, which is not what you are trying to do!

### Variables

The TI-30XA cannot solve algebraic equations. You need a more advanced calculator for that, like the TI-89.
