## How to Subtract 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:

**a × 10 ^{b} ; 1 ≤ a < 10**

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 difference between two scientific notations:

**Step 1:**Enter the two scientific notations in the given input boxes.**Step 2:**Now equal the exponent power in both scientific notations.**Step 3:**Now subtract the final scientific notation values.

Note: For example 5.8 × 10^{2} and 5.64 × 10^{4}. Here 5.64 × 10^{4 }which is having the highest power. Now try to convert 5.8 × 10^{2} in form of 10^{4} i.e., 0.058 × 10^{4}

Let us see an example to understand briefly.

**Solved Example:**

Subtract two scientific notations 7.8 × 10^{2} and 12.8 × 10^{4}

**Solution:**

Given: Scientific notation1 = 7.8 × 10^{2} and scientific notation2 = 12.8 × 10^{4}

Now equal the exponent power in both scientific notations.

Scientific notation1 = (7.8 / 10^{2}) × (10^{2} × 10^{2}) {Multiply and divide with 10^{2} to equal the exponent power of 10 in scientific notation2}

= 0.078 × 10^{4}

Scientific notation2 = 12.8 × 10^{4}

Now Subtract the two scientific notations 0.078 × 10^{4} and 12.8 × 10^{4}

= (0.078 - 12.8) × 10^{4}

= -12.722 × 10^{4} or -1.2722 × 10^{5}

Similarly, you can try the calculator to find the difference between two given scientific notations:

- 6.24 × 10
^{5}and 5.235 × 10^{2} - 1.04 × 10
^{5}and 0.458 × 10^{4}
