# Scientific Calculator

Our scientific calculator is available in both blue and pink. Cell phone users may need to flip their phones horizontally to view all functions.

Below are scientific calculator functions and how each one works:

ButtonMathematical Function
Minus sign, subtracts values
+/-, (-), or NEGThe minus or subtraction symbol can make a positive number into a negative number on a scientific calculator. Note that this is usually a different button that looks like a +/-, a NEG button for negation, or a minus sign enclosed in parenthesis (-).
×or *Multiply sign, multiplies values
÷ or /Division sign, divides values
%Percent sign, makes values into a percentage
^, yx or xy Exponential sign, a value raised to the power of x

## Scientific Calculator Buttons and Functions

Authored by Jose Abuyuan on June 25, 2020

Calculators come in handy every day. With the advent of computers and smartphones, people have access to calculators in any digital device. We use it to calculate change or discounts when we buy products.

But if you need to compute more complex math problems, you’ll need more than the basic calculator. If you’re a student in high school, you need to solve advanced math problems that involve square roots, exponents, and trigonometry.

In this guide, we’ll introduce the scientific calculator and how different it is from the regular calculator. Then, we’ll talk about its different buttons and how each function works.

### What is a Scientific Calculator? A scientific calculator is programmed to compute advanced mathematical problems. You’ll notice it has more buttons than a regular calculator. These keys perform functions such as calculating quadratic equations, cube roots, and trigonometry, to name a few. If you need to solve multiple operations with exponents, logarithm, or pi (π), this is the right calculator use.

### How Do Scientific Calculator Buttons Work

Extra buttons on a scientific calculator do more than basic operations. We’ll show what each button or function looks on a scientific calculator. Then, we’ll explain how they are used to solve math problems.

Please note that scientific calculators come in different brands and models. While they look similar, others may use different symbols or have added functions. In this case, we’ll focus on the basic functions common to all scientific calculators.

Below are scientific calculator functions and how each one works:

### Scientific Notation

Scientific calculators have many uses. One of its major functions is allowing users to input scientific notation . Scientific notations are are used for unusually large or small numbers. Most of the time, these values take up many decimal places and cannot be written with a decimal point.

For example, the weight of the Earth is approximately 6,000,000,000,000,000,000,000,000. That’s a lot of zeros; 24 to be precise.

If you’re calculating this number, entering many zeros is time consuming. In scientific notation, this value is written as 6 × 1024. Scientific calculators can input this exact notation including the exponent. How do you enter scientific notation? For example, if your number is 6 × 1024, just follow these steps:

1

Press 6 on the calculator.

2

Then press the multiplication ×button.

3

Next, type the number 10.

4

Then, tap the exponent key. This key varies on scientific calculators, but it will look something like (Exp), (xy), (ax), or (^).

5

Finally, press Enter or the equal (=) button. The equation is automatically read as a scientific notation.

### Order of Operations

Another advantage is solving advanced formulas with order of operations. Regular calculators cannot compute multiple operations and give the right answer.

Let’s have a simple example. For instance, you need to solve this equation:
4 + 3 × 5

According to the order of operations (PEMDAS), 3 should be multiplied by 5 before adding 4. If you simply add 4 and 3 and multiply it by 5, you will get the wrong answer. In a scientific calculator, you can enclose 5 and 4 in a parenthesis, and the equation will look like this:
4 + (3 × 5)

It will solve in the correct order. 3 times 5 is equal to 15. Then, when you add 4, the answer is 19.
4 + 15 = 19

A scientific calculator can input long and far more complex equations. It has a parenthesis function ( ) that lets you set which operations to solve first. This function works like writing equations on paper, solving them in order.

### Why Do People Need a Scientific Calculator? Scientific calculators help solve mathematical problems in various scientific fields. Today, scientific calculators are essential tools for the following scientific fields:

• Engineering
• Physics
• Chemistry
• Medicine
• Calculus
• Statistics

Modern society owes a lot to technological developments done by scientists. These paved the way for important inventions such as the television, computers, and telecommunications. We have scientists to thank for efficient water filtration systems, electricity, and transportation.
