# Q: How is the number 1 written in Scientific Notation?

A: 1 x 100

## Why is 1 written as 1 x 100 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 1 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: 1
• New Number: 1.

### Step 2

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

 New Number: 1 . Decimal Count:

There are 0 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

b = 0

Now the whole thing:

1 x 100

100 = 1 x 1 = 1
