Calculations…not only for professionals in finance, but all of us, in one way or another, are adding prices or subtracting expenses, and so on. And the tool which helps us in this endeavor is the trusty calculator.
With advances in our smart accessories, we can use our smartphones/watches to compute, but nothing is better than a real calculator when you need to tally your numbers.
In this post, we will examine calculators. Most of us think all calculators are the same. But this could be further from the truth. Hopefully, the points we raise, information we share, can assist you in selecting and purchasing the best calculator for you!
How to Choose Calculators in the Philippines – Buying Guide
When calculating numbers, whether it be for household expenses or business proposals, we need accuracy and desire speed. Therefore, the ease in both pushing the keys and viewing the display screen are instrumental.
It is said that a calculator, if used properly, can be used for ten years. Which is another reason, it is advisable to select the most suitable calculator for you! The following are some of the factors you should consider when purchasing a calculator.
The Size of the Calculator
From calculators fitting in your pocket to those the size of a tablet, there are many sizes to this product. Though a large, tablet-sized calculator will have a display easy to view, the loss of desk space due to size is a point to consider. However, a calculator that is small will have the compact keys gathered without ample space between the keys, making input mistakes easier to occur.
Therefore, when considering size, our recommendation is to consider the space between the keys, as accuracy is one of the main reasons we purchase a calculator. And, when in doubt, go with the bigger sized calculator.
Key Size and the Width of the “Gap”
If the keys of the calculator are small, it is most likely the gap between the keys will be narrow as well. The narrow gap means the chances of pushing two keys at the same time will increase, therefore raising the probability of errors. Who needs the stress of having to recalculate the figures due to an error in inputting the numbers? Therefore, we recommend examining both the size of the calculator and the width between the keys before purchase.
As a general rule, we recommend looking at calculators that are at least as large as the palm of your hand.
Number of Digits in Display
For bookkeeping exams in Japan, some of the questions involve calculation in the 100 million range (100,000,000). Having a small display will slow down the calculations and add unnecessary stress and errors. Again, a general rule, 12-digit displays are the best but at least 10 digits (12345678910) is the minimum.
As you become accustomed to your calculator, the speed of input will increase. And you will find that instead of “pushing” the keys, you are beginning to naturally “strike” them. If you have a lightweight calculator, the force of the input may cause the key to misalign, causing errors in the calculator’s interpretation of your input. Therefore, a slightly heavier, sturdy calculator is recommended.
We also recommend (if possible) purchasing a calculator with rubber anti-slip pads on the backside. In addition to preventing damages/scratches to your desk, the lack of slide will prevent the calculator from moving around, allowing ease of accurate and speedy calculations.
There are many functions within a calculator. But even within all these functions, we have picked up a few functions which we feel are important deciding factors.
Key Rollover Function
Imagine typing on a keyboard. You want to write the word “dog.” But as the right hand and left hand move independently, your left hand is still pushing “d” when the right one types “o.”
Key rollover allows the “o” to be inputted while the “d” is still being pushed. And like the keyboard, the key rollover function is the same. Therefore, users are not penalized for having speedy fingers.
However, do note that if the key “1” and “2” are pressed at the exact same time, “12” will not appear. The key “1” must be pushed before “2” for “12” to appear. The calculator scans the numbers based on the input order.
Based on the calculator, users have the option to choose 2-key rollover or 3-key rollover. For purchasing, a 3-key rollover is a good choice.
Imagine having to tally the results from multiple calculation problems. You input the figures from problem 1, write down the answer. You input the figures from problem 2, write down the answer. In the end, you have to input the answers from problem 1, 2, and so on to get the grand total. Isn’t this tiresome?
If your calculators had the GT or Grand Total function, this tedious writing down and inputting would vanish!
Look at the following example
While calculating problem 1 and 2, the calculator will only display that problem’s digits, but the GT function allows the results of these two calculations to be stored in the internal memory. If the GT key is pressed at the end, the sum of the two calculation results, 1700 (1500+200) will be displayed.
This function is useful in both bookkeeping examinations as well as for calculations in everyday life. Therefore, we recommend seeking a calculator with this function.
Like the GT function, the “M” memory function is another must-have function. The memory function allows special numbers or calculation results to be temporarily stored in the calculator’s memory.
M+: add to memory
M-: subtract from memory
MR (or RM): recall memory (recall the stored values)
MC (or CM): clear the memory (delete the stored values)
Both of these functions are so crucial in the bookkeeping world that is often remarked: “those who master the grand total and memory functions are the masters of the calculator!” Therefore, we strongly recommend utilizing (and mastering) these functions.
A calculator is often kept on the desk. Therefore, the light from a window or the room’s lighting (bulb, etc.) can cause a glare, affecting how the numbers can be seen. Having a tilt display allows the user to adjust the display screen to the best position according to the lighting situation.
However, many calculators which do not have this function have a sloped display. Therefore, the tilt display function does offer convenience but isn’t a very necessary function.
Placement of the Keys
The three major calculator manufacturers are Casio, Sharp, and Canon. The major difference between the three manufacturers is the placement of the keys. Where the keys are located affects the ease of use, this is a major consideration when choosing the calculator.
