Tips on using the HP 12 c Calculator

About Us


Dear visititantes this blog was created to work the academic discipline of English, the students are FATEC (Faculty of Technology) are studying Financial Management. And our theme was how to USE THE CALCULATOR HP and for you who are interested in learning how to do financial calculations on the HP 12c calculator, put walkthrough of financial calculations.The goal of our work is to show the ease to solve mathematical problems and resolution of statistical operations with the use of the HP-12 c calculator, through activities that allow students and teachers to identify and use the functions provided by the calculator and perform calculations so practical.


Learn more about the various functions and Archritecture groups of the HP-12 c Calculator 




HP 12 c calculator is Ideal tool for professionals and students

HP 12 c Platinum Financial Calculator is an important tool for students, teachers and professionals from various fields of knowledge. With it, you can perform simple calculations to complex to simplest way and agile thanks to its more than 130 financial and statistical, mathematical functions, in addition to extensive memory memory.
Another benefit of the HP 12 c Platinum is its convenience to be carried, because it has compact dimensions (12.9 x 7.9 x 1.5 cm) and light (120 grams). Your battery 3V type CR2032 also ensures longer life and autonomy, as well as the auto-off feature, which provides economy after periods of idleness for more than 10 seconds. To ensure a more direct line of reasoning during the formulation of its calculations and obtain a better use of memory, this HP Calculator uses the RPN (reverse polish notation) input logic. On the other hand, if you prefer the algebraic method, this flexibility is available according to your need or preference.
If you need flexibility in their financial or business calculations, the HP12C Platinum has memory for up to 30 cash flows and the following functions: "% change", "methods of Depreciation", "price and income from securities", "Depreciation" and "TVM (loans, savings and Rental)".
The same flexibility for your financial calculations is also guaranteed for several operations involving statistics as "statistical analysis", "Projection", "Linear regression, correlation and coefficient" and "standard deviation, mean and median". For mathematical calculations, the HP 12 c offers "potentiation, square root and square", "natural logarithms and exponentials", "Rounding" and "Factorial and inverse of numbers", as well as resources for data management and time with their "date Arithmetic".
HP 12 c Platinum Financial Calculator can still take over a function for users who have mastered programming, since it supports memory up to 400 steps. With this machine, you can install programs for series of repetitive calculations and equations, as well as applications and other programming functions available with RPN logic.

Basic calculations on HP 12C


Connecting to press to turn ON and ON again.


 Cleaning the HP 12C calculator display

Press the button CLX.

SUM of two numbers on the HP 12 c calculator.


Sum of three numbers


  More Examples:

Make: 14+20-4


Make: 23+7÷15


Make: 5x5

Make: 5²

Make: 5%  of 250

Calculate the percent difference between two numbers

An object that was costing $ 1,000 now cost $ 1,200.
 What is the percentage increase been?


For those who still do not have the HP 12C calculator, the calculator will post the link online, it has some limitations, but to do the main calculations.

How to calculate the Interest Rate


The interest rate represents the cost of using the money. Therefore, the price paid by anyone for the use of money or product that you have been assigned.

Example: when buying a fridge worth sight $ 1,299 .00 and the provision would input 0 and 20 plots of R$119,00. What would be the interest monthly charged this provision? 
And we reckon on HP 12 c calculator is pretty simple.

-Tell the calculator that comes postecipada series (if it is already configured, no need to do this step): g end;
- Move the value in sight: 1299 CHS PV;
- Bid the number of installments: 20 n;
- Bid the value of parcel:119 PMT;
- Press i for know the fee.


Therefore, the interest rate charged is 6.62% to month.

Note: the key CHS reverses the sign of the value in cash, making it negative. This needs to be done because the PV signal should always be opposite the PMT signal.

Calculation of the benefit in the System Price



Hello!
Now we teach the system how to calculate price. This calculation is used primarily for you who will buy a car financed and would like to know the value of benefits.l benefits.


Example: Suppose a person will buy a car $ 35,000 .00 in 48 equal instalments, with an interest rate of 1.5% per month. What is the value of the monthly installment?

Data provided in the problem:

-financed amount: $35,000(PV)
-the number of benefits: 48 (n)
-interest rate: 1.5 (i)

Calculating

-Bid values : 35,000 PV 1.5 n 48 i;
-PMT press to get the value of the benefit;

     Note: The value is negative because the PMT always has the opposite sign of PV.

Basic Calculations of financial Mathematics


Good afternoon! 
Today we will teach you how to make Simple Interest calculations.

Example: If it is applied the principal of $ 2,750 .00 during 1 year and a half (18 months) at a rate of 1.5% per month, which will be the amount at the end of this term?
 We know of three variables (principal, interest rate and term) and we want to calculate the amount. To obtain this value with the financial calculator, simply enter the value of these three variables and ask for the calculation of the variable we wish to calculate. Below is the command sequence for the calculation in the HP 12C.


In the first command line was made to clean the financial memories, something that should always be done when you start solving a financial calculation problem (need not be done if you are going to do a multiplication, a calculation of percentage or with dates). In the second line we inform the main value calculator. In the third we reported the value of the interest rate. In the fourth line we inform the period of operation. Finally, in the fifth line is prompted calculating, simply by pressing the key that corresponds to the variable we wish to calculate. The display will show the result.

How to calculate the average and standard deviation


        At HP 12C can do these calculations very quickly

As an example to illustrate the calculations, suppose that 5 people have the following weights: 58Kg, 65Kg, 77kg, 85Kg and 90Kg. The mean and standard deviation of this data set are calculated as follows:



1- To launch the calculator data set, enter each value followed by the key  58 Σ+ 65Σ+ 77 Σ+ 85 Σ+ 90 Σ+;
2- To find the average just press g then the key (the same key of 0);
3- To find the standard deviation og followed just press the S key (the same key.);
