# Q: How is the number 102 written in Scientific Notation?

A: 1.02 x 102

## Why is 102 written as 1.02 x 102 in scientific notation?

The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.

Calculating scientific notation for a positive integer is simple, as it always follows this notation:

a x 10b

Follow the steps below to see how 102 is written in scientific notation.

### Step 1

To find a, take the number and move a decimal place to the right one position.

• Original Number: 102
• New Number: 1.02

### Step 2

Now, to find b, count how many places to the right of the decimal.

 New Number: 1 . 0 2 Decimal Count: 1 2

There are 2 places to the right of the decimal place.

### Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 1.02

b = 2

Now the whole thing:

1.02 x 102

### Step 4

102 = 100 x 1.02 = 102
