# Scientific Notation

Enter numbers with powers and click calculate button to find the arithmetic operations of two scientific notation numbers

## Scientific Notation Calculator

Scientific Notation Calculator is used to add, subtract, multiply, and divide scientific notation numbers.

## What is meant by Scientific notation number?

Scientific notation is used to express large numbers in short form for easiness in calculations reason why the scientific notation method applies because when a number approaches infinity then with the help of scientific notation number it can be written in short form which is easy to understand and solve easily.

**For Example **

The number **“**33000000000000000000000000000000**”** can be written as **3.3 ****× 10 ^{31}**

## How to perform arithmetic operations on Scientific Notation numbers?

**Example 1:**

Add these scientific notation numbers

2.3 × 10^{2 }+ 7.2 × 10^{7}

**Solution**

**Step 1:**

Expanding the scientific notation numbers

= 230 + 72000000

= 72000230

**Step 2:**

Again, converting into Scientific notation

= 7.200023 x 10^{7}

**Example 2:**

Subtract these scientific notation numbers

5.234 × 10^{4 }- 1.2 × 10^{2}

**Solution**

**Step 1:**

Expanding the scientific notation numbers

= 52340-120

= 52220

**Step 2:**

Again, converting into Scientific notation

= 5.222 x 10^{ 4}

**Example 3:**

Multiply these scientific notation numbers

1.1 × 10^{3 }* 1.3 × 10^{2}

**Solution**

**Step 1:**

Expanding the scientific notation numbers

= 110*130

=143000

**Step 2:**

Again, converting into Scientific notation

= 1.43 × 10^{5}

**Example 4:**

Divide these scientific notation numbers

2.1 × 10^{6 }÷ 1.4 × 10^{4}

**Solution**

**Step 1:**

Expanding the scientific notation numbers

= 2100000 ÷ 14000

= 2100 ÷ 14

= 300 ÷ 2

= 150

**Step 2:**

Again, converting into Scientific notation

= 1.5 × 10^{2}
