Introduction
Calculators have become an essential tool for students, scientists, and professionals alike. They help us perform basic arithmetic operations with ease and also solve complex mathematical equations. However, many people are often puzzled by the mysterious letter 'E' that appears on their calculators. What does it mean? Is it an error message or some secret code? In this article, we will unveil the mystery of what does E mean on the calculator and how to use it for calculations.
The Scientific Notation
The 'E' that appears on the calculator stands for exponent or power of 10. It is used for scientific notation, which is a way of expressing very large or very small numbers in a more convenient form. For example, the speed of light is approximately 299,792,458 meters per second. This number is difficult to read and write, so scientists use scientific notation. They represent it as 2.99792458 × 10^8 m/s. Here, 10^8 is the exponent, and it means 10 raised to the power of 8. The base number 2.99792458 is multiplied by 10^8 to get the actual value of the speed of light in meters per second.
Example of Scientific Notation
Let's take another example to understand scientific notation better. Suppose we want to express the mass of the earth, which is approximately 5,972,000,000,000,000,000,000 kg, in scientific notation. We can write it as 5.972 × 10^24 kg. Here, the exponent is 24, which means 10 raised to the power of 24.
Calculating Large Numbers
The 'E' button on the calculator is used to enter numbers in scientific notation. For example, if you want to enter 2.99792458 × 10^8 into the calculator, you can press 2.99792458 followed by the 'E' button and then enter the exponent 8. The calculator will display the actual value of the number as 299,792,458. You can perform arithmetic operations on large numbers in scientific notation such as addition, subtraction, multiplication, and division.
Table Comparison
| Operation | Example | Result |
|---|---|---|
| Addition | 4.5E4 + 3.2E5 | 3.65E5 |
| Subtraction | 7.8E6 - 5.6E5 | 7.24E6 |
| Multiplication | 2.5E2 * 6.4E3 | 1.6E6 |
| Division | 8.5E7 / 2.1E4 | 4.04761905E3 |
Calculating Small Numbers
The 'E' button on the calculator is also used to enter small numbers in scientific notation. For example, if you want to enter 0.0000000015 into the calculator, you can press 1.5 followed by the 'E' button and then enter the exponent -9. The calculator will display the actual value of the number as 1.5E-9. You can perform arithmetic operations on small numbers in scientific notation such as addition, subtraction, multiplication, and division.
Table Comparison
| Operation | Example | Result |
|---|---|---|
| Addition | 4.5E-6 + 3.2E-7 | 4.82E-6 |
| Subtraction | 7.8E-8 - 5.6E-9 | 7.24E-8 |
| Multiplication | 2.5E-5 * 6.4E-3 | 1.6E-7 |
| Division | 8.5E-7 / 2.1E-4 | 0.00404761905 |
Conclusion
The 'E' button on the calculator is not a mystery anymore. It is used for scientific notation, which helps us to represent large or small numbers in a more convenient form. You can use it to perform arithmetic operations on large and small numbers with ease. The tables above show some examples of addition, subtraction, multiplication, and division using scientific notation. However, be careful while entering the exponent as a small mistake can lead to a significant error in the result. Practice using the 'E' button on the calculator, and you will become an expert in performing calculations with large or small numbers.

People also ask about Calculate with E: Unveiling the mystery of What Does E Mean on Calculator:
- What is the meaning of E in calculator?
- How do you use E on a calculator?
- What does EE mean on a calculator?
- What is the difference between E and EE on a calculator?
- Why is E used in scientific notation?
E on a calculator stands for exponential notation or scientific notation. It represents a number multiplied by ten raised to a power.
To use E on a calculator, enter the base number followed by the E symbol and the exponent. For example, to express 6.02 x 10^23 in scientific notation, you would enter 6.02E23.
EE on a calculator is a shortcut for entering scientific notation. It stands for enter exponent. For example, to enter 1.2 x 10^6 in scientific notation, you can simply enter 1.2 EE 6.
E and EE on a calculator both represent exponential notation or scientific notation. The only difference is in how they are entered. E requires the exponent to be entered right after the symbol, while EE allows the exponent to be entered separately.
E is used in scientific notation because it provides a compact way of expressing very large or very small numbers. By using exponential notation, numbers that would otherwise require many digits to write out can be expressed using fewer digits and a simpler format.
