Are You a Better Calculator Than an LCD Calculator?

LCD Calculator With the rise of smartphones and other handheld devices, many people have turned to calculators for basic math and financial tasks. But which calculator is best for you? Check out this article to find out!

# What is an LCD Calculator?

LCD calculators are often thought of as being inferior to traditional mechanical calculators. However, there are a few things to consider when making this judgment. LCD calculators usually have a more comprehensive range of functions and are more user-friendly. Additionally, they tend to be cheaper than traditional calculators.

## How Does an LCD Calculator Work?

LCD calculators are a series of switches and light-emitting diodes (LEDs). The buttons control the display, while the LEDs indicate the result of a calculation. When you press a key on the LCD calculator, the switches close a circuit, turning on the LEDs behind each key.

This causes the LEDs to light up in sequence from left to right. The first LED lights up when the switch is closed and stays lit until the next switch is pressed. The second LED lights up when the first LED is turned off and stays lit until the next button is pressed or until you hit another key on the calculator. The third LED lights up when both other LEDs are turned on and stays lit until you hit another key.

### Advantages of using an LCD Calculator Over a Standard Calculator

There are a few advantages to using an LCD calculator over a standard one. For starters, the LCD panels are much easier to see in bright light, making them ideal for use in classrooms or offices with high-powered lights. Additionally, they're typically faster and more accurate than standard calculators, making them a better option for complex calculations.

#### Disadvantages of Using an LCD calculator Over a Standard Calculator

Are you a better calculator than an LCD calculator? The answer to this question depends on what you mean by "better." An LCD calculator may be faster if you're referring to speed because it displays the results immediately. However, if precision is your main concern, a standard calculator will usually be more accurate. The main disadvantage of using an LCD calculator is that they tend to wear out faster than standard calculators.

##### How to Choose the Right LCD Calculator for You

Like most people, you probably use a calculator for various household tasks—from figuring out restaurant tips to totaling the grocery bill. But which one is best for you?

To help you make an informed decision, we've put together a guide to choosing the right LCD calculator for your needs. In this article, we'll discuss the different types of calculators available on the market and highlight some key factors to consider when choosing one.

###### First things first: What do you need your calculator for?

There are a few things to remember when deciding which type of calculator is right for you. First, consider what kind of tasks you'll use it for. Do you need a basic scientific calculator for math class? Or do you need something more versatile, like a graphing calculator that can handle calculus problems?

Next, consider what type of display you need. Most calculators come with an LCD screen (like the Casio fx-9700G). Still, some mechanical calculators use buttons and keys (like the TI-89) and electronic calculators with a touch screen (like the HP EliteBook Folio G1).

And finally, consider your budget. There are a lot of great calculators out there, but not all of them are affordable. If you're on a tight budget, consider purchasing a calculator with fewer features or a lower price point.

Now that you've got an idea of what to look for let's take a closer look at some of the best LCD calculators available on the market.

### Basic Scientific Calculators

A basic mechanical calculator is probably your best bet if you're just starting in calculus or need a basic scientific calculator for general math problems. They're affordable, easy to use, and have a few simple functions (like square roots and absolute values) that you'll likely need.

Some good choices for basic scientific calculators include the Casio fx-9700G and the Texas Instruments TI-86 Plus Silver Edition.

Graphing Calculators

Consider getting a graphing calculator if you need something more versatile than a basic scientific calculator. Graphing calculators can handle complex algebraic equations and can help you plot linear and nonlinear graphs. They can also be used to solve systems of equations and perform other advanced mathematical calculations.

### How to Calculate Basic Math Functions on an LCD Calculator

You're not alone if you've ever struggled to calculate essential math functions on an LCD calculator. Even experienced mathematicians sometimes find it hard to work out the correct equation on a screen. Luckily, there's a simple workaround: use a calculator with a keypad!

Here are four essential math functions you can easily calculate using a keypad calculator: addition, subtraction, multiplication and division. To do these calculations, follow these steps:

1. Press the "plus" or "minus" key on the keypad to activate the function buttons.
2. Enter the first number in the add/subtract window (the number you want to add or subtract), and then release the "plus" or "minus" key.
3. Enter the second number in the window (the number you want to multiply or divide by), and then release the "plus" or "minus" key.
4. Press the "/" key on the keypad to activate the decimal point button. Then enter your final number in the window, and release "/."

These four essential math functions will work no matter which calculator you use: a desktop computer, a laptop, a handheld device, or even an iPod!

#### Tips for Better Accuracy when Using an LCD Calculator

It can be challenging to get the most accurate results using an LCD calculator. Here are a few tips to help you get the most accurate results:

1. Make sure your numbers are entered correctly. If your numbers are incorrect, your calculator will not be able to give you accurate results.
2. Try to use as many decimal places as possible. A more significant number of decimal places will result in a more accurate calculation.
3. Avoid parentheses and square roots. Parentheses and square roots can often complicate calculations, making them more difficult to perform accurately.

Conclusion

There are many great things about using an LCD calculator like they're easy to carry around and don't take up much space. But there are also some definite advantages to using a calculator with more features — like performing calculations in different modes and solving equations. So which one should you choose? The answer is: that it depends on the task at hand. If you need to solve simple algebraic equations or find your square root quickly, an LCD calculator will be just fine. But a calculator with more features will be better suited for the job if you need to do more complex calculations or work with variables.
