Adding Scientific Notation Calculator

Scientific notation is a method for expressing a given quantity as a number having significant digits necessary for a specified degree of accuracy, multiplied by 10 to the appropriate power. It is a form of presenting very large numbers or very small numbers in a simpler form.

How to Add Two Scientific Notations?

A scientific notation is a form of writing a given number, an equation, or an expression in a form that follows certain rules. Writing a large number like 15.5 billion in its number form is not easy but also time-consuming and there are chances that we may write a few zeros less or more while writing in the number form. So, to represent very large or very small numbers concisely, we use scientific notation. The general form of scientific notation is:

Where 'a' represent any number between 0 to 10 ( greater than 0 and lesser than 10) and 'b' is any number.

Please follow the below steps on how to find the sum of two scientific notations:

• Step 1: Write the two scientific notations.
• Step 2: Now equal the exponent power in both scientific notations.
• Step 3: Now add the final scientific notation values.

Note: For example 5.8 × 10² and 5.64 × 10⁴. Here 5.64 × 10⁴ which is having the highest power. Now try to convert  5.8 × 10² in form of 10⁴ i.e., 0.058 × 10⁴

Let us see an example to understand briefly.

Solved Example:

Add two scientific notations 7.8 × 10² and 12.8 × 10⁴

Solution:

Given: Scientific notation1 = 7.8 × 10² and scientific notation2 = 12.8 × 10⁴

Now equal the exponent power in both scientific notations.

Scientific notation1 = (7.8 / 10²) × (10² × 10²) {Multiply and divide with 10² to equal the exponent power of 10 in scientific notation2]

= 0.078 × 10⁴

Scientific notation2 = 12.8 × 10⁴

Now add the two scientific notations 0.078 × 10⁴ and 12.8 × 10⁴

= (0.078 + 12.8) × 10⁴

= 12.878 × 10⁴ or we can write it as 1.2878 × 10⁵

Similarly, you can try the calculator to find the sum of two given scientific notations:

• 6.24 × 10⁵ and 5.235 × 10²
• 1.04 × 10⁵ and 0.458 × 10⁴
