# Scientific Notation Formula

Scientific notation expresses a very large number like 843000000 and very small numbers like 0.000000058 in a shorthand way. Many practitioners work with scientific notation as it is easy to compute and manage.

**Scientific Notion is written in this form:**

N $\times$ 10$^{x}$.

Where,

N is a number and which lies between 1 and 10, i.e., (1 $\leq$ N $\leq$ 10),

x is an integer.

We need to move the decimal point until it becomes a number and then make the exponent either positive or negative. If the decimal is moved to right, then the exponent is positive; whereas when the decimal is moved to left, then the exponent is negative. Positive exponents mean the number is larger and negative means smaller number.
