Remember in Scientific Notation there is only 1 whole number

(1 place before the decimal place).

The rest of the numbers are written as decimals times 10 to a power.

That power is the number of places the decimal had to move in order to accomplish this requirement.

The power is positive if the decimal moved to the left.

The power is negative if the decimal moved to the right.

If you are asked to convert the word form or short word form of numbers into Scientific Notation. First convert the word form or short word form into standard form (all numbers), then write as scientific notation.

Four million six hundred thousand first becomes

4, 600.000 then becomes 4.6 x 10 to the 6th power
