Scientific Notation
An ordinary quarter contains about 97,700,000,000,000,000,000,000 atoms. The average size of an atom is about centimeters across.
The length of these numbers in standard notation makes them awkward to work with.
Scientific notation is a shorthand way of writing such numbers.

9. Ex 2: Write 497.23 in scientific notation.
Helpful Hint! If the number is getting SMALLER, the exponent is getting LARGER. If the number is getting LARGER, the exponent is getting SMALLER.

10. Ex 3: Write 0.0043 in scientific notation.
Helpful Hint! If the number is getting SMALLER, the exponent is getting LARGER. If the number is getting LARGER, the exponent is getting SMALLER.

11. Ex 4: Write 90,080 in scientific notation.
Helpful Hint! If the number is getting SMALLER, the exponent is getting LARGER. If the number is getting LARGER, the exponent is getting SMALLER.

Helpful Hint! If the number is getting SMALLER, the exponent is getting LARGER. If the number is getting LARGER, the exponent is getting SMALLER.

16. How to read scientific notation on calculator
Multiply 4,000,000 x 4,000,000 on calculator
=1.6 E12
“E” Stands for “exponent”
So, this is 1.6× 10 12
