When choosing a scientific calculator, there are a number of criteria to consider. As always, you should be careful before making a purchase.
The main reason we buy a calculator is to make faster calculations. You should choose a model whose programming allows you to calculate all the problems in your discipline. Most calculators can help you calculate normal mathematical problems, logarithms, fractions, statistics, probabilities, etc. If the scientific calculator you choose can handle the math problems in your discipline, then it's a good calculator.
If you're on construction sites, you may not need a calculator with lots of technical buttons. You may need a simple scientific calculator that will handle basic math problems. If you work in the discipline that uses advanced math, you really need to look at the advanced discipline. There is a specific scientific calculator that is programmed and designed for all math problems.
Users who work in the field need simple scientific calculators that they can carry easily. Therefore, it is important to choose a scientific calculator that can fit in a bag or pocket. Compact scientific calculators are easier to hold and use because it has small, soft buttons. However, if you work in the complex engineering project office, a more advanced scientific calculator will be recommended.
Durability is very important when choosing a scientific calculator. You should look for a calculator that comes with a dust cover, a waterresistant display, and buttons that remain easily identifiable after several uses. You should also choose a calculator with a clear display. You'll need to look at the manufacturer's listed features to see if you can use the calculator in the sun. Some screens display blurred figures when used outdoors.
If this is the first time you are going to use a scientific calculator, there will obviously be some getting used to. So make sure the model is relatively easy to use or at least that the manufacturer offers an easytounderstand tutorial. If you are already using a scientific calculator, but decide to change manufacturers, there will certainly be a new learning curve as well.
The most obvious way to learn how to use a scientific calculator is to read the manual. If you have a calculator that doesn't come with a manual, you can usually search for the manual online and download it. If not, you need to do a little experimentation.
The main differences in how calculators work are in the order of operations. For example, we want to calculate 3 + 5 x 4. According to the order of operations we learned in school, the 5 and the 4 must be multiplied by each other before adding the 3. Your calculator may or may not know this.
If you mark 3 + 5 x 4, some calculators will give you the answer 32 and others will give you 23 (which is the correct answer). This is the type of calculation you need to try on your new calculator to understand how it works.
It's the same with the square root. For the square root 4, you know the answer is 2. With your new scientific calculator, you need to figure out if you should type 4 and then press the √ key or if you press the √ key and then type 4.
The scientific calculator can perform various complex calculations, including trigonometry. A scientific calculator can also handle logarithms and exponentiation calculations. That's all a high school student could need. Most scientific calculators have a singleline display, like on basic calculators. But sometimes the display is 2 lines.
Each line can accommodate 10 to 12 digits, with additional digits for floating point arithmetic. Typically, highend scientific calculators offer boolean calculations, hexadecimal calculations, fractions and probability calculations, complex numbers, physical constants, unit conversion, calculus and matrix calculations.
A graphing calculator offers more advanced and complex features. In some industries, this is a real advantage over simple scientific calculators. When solving complicated functions, you will need a graphing calculator. This capability is invaluable in various types of math problems.
Graphing calculators are most often used in physics, engineering, statistics and some areas of applied biology. A graphing calculator is also a calculator that has a large screen for visual representation of the problem. Overall, graphing calculators are more sophisticated and offer more calculation features.
Scientific calculators are a tool to help with basic algebra and statistics. On the other hand, a graphing calculator is a scientific calculator with a high resolution screen and includes the ability to plot coordinates and graph functions. Your choice will therefore depend primarily on the field of application.
Invest in the best.
A graphing calculator is a longterm investment. While new models come on the market from time to time, the basic functions of calculators remain the same. If you buy a fullfeatured scientific calculator, it can last for many years.
Having WiFi on a scientific calculator is always a plus.
Some highend scientific calculators have WiFi connectivity so that data from other scientific devices such as weather gauges, decibels, photometers, electronic thermometers, etc., can be read and evaluated.
Use the memory function to solve logarithms.
A highend scientific calculator is perfect for calculating logarithms, especially those with builtin memory that gives you the ability to store some equations. If you're working on something that requires multiple sessions, you can have your calculator store what you've already entered into the device. This makes it easier to test and correct.
Be sure to check that the scientific calculator you are using is approved for use in the exams.
If you are in high school or college, you need to know if the scientific calculator you have is approved and allowed on exams. Always ask your teacher. Many exams have very strict requirements about which calculators are allowed and which are not.
Don't abuse your calculator!
Technology encourages laziness. It's well known that calculator users tend to abuse them, even for basic mental math operations. Don't adopt this kind of reflex! The more you exercise your brain, the better it will be sharpened. So, use the scientific calculator only for complex operations.
The best scientific calculator depends on your needs and budget. Read our buying guide for the best products available.
For most scientific calculators you will need to use an ab/c key. Let's say you wanted to calculate 1/3 + 1/4; then here's how to do it: 1, ab/c, 3, +, 1, ab/c, 4, = (commas are for separation only and are not inputs).
This will give you the inverse of a number. For example, 4, x 1 will give you 0.25. On most scientific calculators, you can convert this to a fraction, 1/4, by pressing ab/c.
On a scientific calculator, parentheses are used to determine the priority in the order of certain operations. For example, if we write 16  8 ÷ 4, we will get 16  2 = 14. If what we really wanted was to do the subtraction first, then we can do it by writing this: (16  8) ÷ 4.
Yes, there are scientific calculators with algebraic memory functions.
