Sometimes your answers will have ugly elements such as root two or root three, but you can always work backwards to match your decimal answer with these irrational ones and your calculator can do that for you too.
From here you can either download the program for free onto your computer and then on to your calculator. Or you can use method 2 and type the code into your calculator by hand. After that, keep scrolling on this page for instructions on what the program does and how to use it. Begin typing in the code shown in the video or image below. Having trouble finding the character or function you see in the code? And then press [enter] [enter]. Then the program will take you to the screen below.
From here you will be asked whether you know either one leg and the hypotenuse or both legs. Scroll to the correct option and then press [enter]. Once you have pressed enter you will be prompted to enter the lengths of either the two legs or the hypotenuse and the leg.
Once you have typed in both lengths and pressed [enter] the program will give you the third side. Calculator Hack 1: The FRAC Key This calculator function will turn any answer in decimal form into fraction form if there is an acceptable way to do so. Calculator Hack 2: Programs There are three programs that I find most helpful.
Also, this is a great Instructable with strong enough descriptions in each step it was enjoyable following along. Reply 5 years ago. Did you make this project? Share it with us! I Made It!

The 5th root of is equal to 2. Keep in mind that the parentheses are necessary otherwise you would raise to the 1st power, divide by 5, and the answer you will get is You can calculate any root using this strategy.
We would usually use natural logarithms base e in finance which is typically abbreviated as Ln x. But there are times we need to use other bases. You can covert base e to any other base by doing the following formula say we are converting to base 10 :.
Be careful when resetting because it will remove any programs that you may store in the calculator. This is how you can reset it:. Keep it in mind that resetting may impact the contrast of your screen. If you really have to reset, then you can change the contrast of the TI 84 Plus screen by pressing the 2nd and then the up arrow or down arrow button. There are times you will be required to do this repeatedly. Here you can find many math program downloads that can help you extend the capabilities of your calculator.
Toggle navigation. You can then start entering the data as shown in the table below: You then just have to scroll to the FV line and press Alpha Enter in order to find the future value. A couple of things to keep in mind: There are either 4 or 5 variables in every time value of money. They correspond to the 5 basic financial keys.
These variables will always give you 3 or 4 and will be asked to find a solution for the other. You can solve these problems by simply entering the variables that you know on the correct lines and then scroll to the line for the variable you wish to find a solution with. You just have to press Alpha Enter so you can get the answer.
We prefer it this way. It will be much easier for you if you can remember to change these 1 for annual compounding, 12 for monthly compounding, etc to the appropriate values for each problem. We placed 10 rather than 0. The future would have come out to Did you notice that we entered the in PV as a negative number? We actually did that on purpose. Financial calculators mostly follow the Cash Flow Sign Convention.
The reason for this is to keep the direction of the cash flow straight. Positive numbers being entered are cash inflows while negative numbers being entered are cash outflows. Use the - instead. For instance, you want to know what the future value is going to be if you left the money invested for 10 years instead of 5.
You only need to enter 10 on the N line and find the solution for FV. The answer that you will find is Solving for the Present Value of Lump Sums The calculations for the present value of a lump sum and the future value is very similar.
How to Solve for the Interest Rate Solving the interest rates is especially helpful for people who recently sold an investment and would like to know what their compound average annual rate of return is.
PV and FV of Annuities We previously learned how to look at the basic time value of money keys and how they are used to calculate the present and future value of lump sums. How to Solve for the Payment Amount Solving for annuity payment is oftentimes necessary. How to Solve for Annuities Due In the previous examples, our assumption was that the first payment would be made at the end of the year which is usually expected.
How to Solve for Perpetuities We occasionally have to deal with annuities that pay forever theoretically instead of for a finite period of time. How to Solve Future Value of Uneven Cash Flows In order to find the future value of these cash flows instead of the present value, we will need to use a bit of genius approach since there is a function to do this. To solve this problem, here are some things to keep in mind: The calculator must not only have the annual cash flows but the cost as well.
Remember that we set the cost to 0 since we only needed the present value of the cash flows. In general, an investment must be paid first before you can receive its benefits so the cost or the initial outlay is said to occur at a time period today for example.
Considerations You must understand all the annual problem principles you have learned still apply for non-annual problems.
Is it possible to calculate the number of days between two dates using the TI 84 Plus? For instance, get the number of days between 25 July and 31 December by typing: dbd YY Whichever way you do it, the answer you will get is days between those two dates.
Is there any other way to find roots other than using square roots of the TI Plus? I only have a key to calculate natural logarithms in my calculator. How can I calculate logarithms to other bases? What should I do to clear the memory of all variables and lists? To exit, press 2nd QUIT. Just remember to be careful not to delete any lists or variables that you need to save. I want to completely reset my TI 84 Plus back to the factory default settings.
How can I do that? Need help downloading these programs? Quadratic Equation Solver A program to solve quadratic equation problem quickly and simply. Pythagorean Theorem Find missing lengths and check if a triangle is a right triangle using the Pythagorean theorem.
