 Although the DM15L is an advanced scientific calculator, and the venerable HP12C is still available, it can easily be used for basic business calculations. I guess it's like driving your Ferrari to buy milk around the corner. Just imagine how much fun buying milk is. So by basic business calculations I mean product margins etc., not financial calculations, I think the HP12C or DM12L is more suited. I have to admit, the HP10Bii Plus is so much more suited to business calculations than both the HP12C and DM15L, but if you can drive around in a Ferrari why bother with a Tata? In any business, you have to calculate margins (MU), gross profit (GP), VAT, or GST. It's all about percentages. The STO and RCL functions of the DM15L are ideal for storing and recalling these percentages that you use over and over. Let's setup a hypothetical situation. The following markups (MU) are used and stored in registers R1 to R9: R0: 15% VAT (1.15) R1: 35% (0.65) R2: 30% (0.70) R3: 25: (0.75) R...

 Solving the equation below on a modern CAS or RPN calculator is quite easy, but doing it on the older HP15C or the latest DM15L is a little different. On an HP35s or HP Prime, even the HP50C enter the equation into the equation writer or solver, then solve for 'x' without thinking much. On the other hand the HP15C forces you to understand the flow of calculations and their relation to each other. In my opinion, a fundamental aspect missing in today's math's education. $$x^{x^2}=256$$ I posted this because I got it wrong and forgot the rules of exponents. A lot of people start from the bottom and work upwards to 'x', while the correct way is working from 'x' down to 2. So $$(x^x)^2 \ne x^{(x^2)} $$ Below is the program you can enter on the HP15C or DM15L (I assume the HP11C will work the same, even the venerable HP41 range, albeit with some changes in key selection. [f][PGRM] [g][P/R] [F][LBL][C] [2] [yx] [yx] [2][5][6] [-] [g][RTN] [g][P/R] To run the p...

 A double exponent equation that is easily solved with the DM15L. The short program stores the keystrokes in the number 2 on the keypad or R2 registry. $${2^3}^x=512$$ To solve for 'x' using a DM15L or HP15C enter the following keystroke program: [f][PRGM] .... (Clears program memory and starts at line 001) [g][P/R] .... (Starts program mode) [f][LBL][2] .... (Stores the program in numeric keypad 2) [3]  .... (The start of the equation with the first value) [yx] [2] [x<>y] .... (swap the x and y registry) (Key 34, third row from the top, fourth column) [yx] [5][1][2] [-]  .... (End of the equation) [g][RTN] [g][P/R] To run the program enter the following Enter a range between 1-5 that you guess the answer should lie  [1] ENTER [5]  .......(Don't press ENTER) [f] [SOLVE] ....... (Select the solver) [2] ....... (The program is stored in the number 2 button) Answer should be = 2, enjoy.

 RPN (Reverse Polish Notation) is a type of keystroke programming that is used in calculators and computer programs to perform mathematical operations. In RPN, instead of writing expressions in the traditional way (e.g. 2 + 3 = 5), the operands (i.e. the numbers) are entered first, followed by the operator (e.g. +). For example, to add 2 and 3 in RPN, you would first enter the number 2, then enter the number 3, and finally press the + key to perform the addition. The result of the calculation (5) would then be displayed. RPN entry [2] [ENTER] [3] [+] Algebraic entry [2] [+] [3] [=] The answer is given in the LCD panel as 5. There is no '=' (equal) sign. The calculation is done when you pressed '+'. The main advantage of RPN is that it eliminates the need for parentheses, which can be confusing and error-prone, especially for complex expressions. (10-5)(3+7x2)  = 85 RPN entry [7] [ENTER] [2] [*] [3] [+] [10] [5] [-] [*] Algebraic entry [7] [*] [2] [+] [3] [m+] ... Store ...

Eskom through its incompetence and greed is slowly ruining the South African economy. It is amazing that one big corporation can have such a significant effect. How is it possible that people in ESKOM see how the company is going down the drain but they do nothing about it. Instead the only focus is to double their salaries. Maybe that is a way of repaying their incompetence. Does the ANC not understand that killing the goose that lays the golden egg will not provide more golden eggs. I heard a comment once about the brain drain in ESKOM and it has been replaced with dung. Very fitting if you see the graphic down below as found on MyBroadband. You can read the full article here . See how incompetent ESKOM is over time Source: MyBoradband The excuse that there is a coal shortage is absolutely nonsense. There are at least 170 coal mines delivering coal every day and coal is heaping up at the ESKOM power plants. The problem is that ESKOM is not buying any coal at the moment. W...

The search function in any mail system is crucial especially if you use it for business.  Microsoft Outlook search function is prone to some error and stops working for no apparent reason.  It does not matter what mail you have, you can connect to gmail, hotmail or your own domain, the search function just stops working. I have searched through all forums but no one recommendation worked for me. I even tried re-installing, running repairs etc. Solving Outlook 365 search function not working I think it has all to do with the size of the outlook.pst file which is the main data file for your emails. Once it reaches a certain size the Outlook 365 search function stops working.  If you don't create new separate data files your main outlook.pst will grow and get bloated. It can easy reach more than 1GB in size. If you  use it for business and have mails as far back as 5 years, the total size can be 30-40GB. There is no way Outlook 365 can run smoothly with such ...

It does not matter what type of business you are in, you need to communicate what you do.  About 10 years ago the Yellow Pages (or similar directories), were absolutely essential. I remember that one year new business placements deadline was shifted a month earlier and I missed it. It was devastating to my business, that was a bad year. In those days you had to wait for the next publication to come out. So what about now. I think you cannot afford not to have a website. I have heard the excuse that my sector is too competitive and I will never land on the first page of Google, Bing or Yahoo.  We'll, just a wakeup call, Google has changed their algorithm and user experience, content quality comes first. The new algorithm even hit big companies such as ask.com because of their weak user experience and shallow information.  That is great for small businesses that want to rank a little higher because they have unique content that is useful to the consumer. So the argum...

The odds are against people who want to start a business. Statistics have shown that 8 out of 10 entrepreneurs who start their own business fail within the first 18 months. It is quite a chilling fact and a big deterrent if you want to start. I don't want to talk about why business fail, because that is a totally different subject. This article is about when to quit a business even if it is not a failure or not making money. You can decide to quit a business venture and sell just because your ROI will be at it's highest. Quitting does not necessary mean stopping what you are doing or taking a new direction. You don't need to quit the whole business, it is healthy to quit parts of it. Shed unprofitable sections and either sell them off or just cut them loose. I call it adapting (in my view anyway). When do you decide when to quit Well you don't decide, or should not decide, to quit business when things are really bad. When things get tough it is often very diffic...

If you own a small business and you are selling the same products that the big guys are selling you are sort of stuffed. There is just no way you will get the number of customers or bottom line they do by competing directly with them. Even if they could sell at cost, they still have a rebate of at least 2.5 - 5.0% with which they can play with. So where lies the secret or better still, the money? Each business sector has it's own strategy, but I will make a few generalizations just to get you going. The first thing you need to believe is that the big boys can be challenged. They are too busy with their own politics and corporate bullshit to even notice you. So don't be scared. I mean really, can you hurt Massmart. They don't think so. Secondly, you must target big corporation's weak points. I will discuss three and how to beat them. Bottom line The sales personnel are more concerned over turnover than bottom line. So the sales person on the floor has a c...
