To convert a number to scientific notation:

  1. write out the number starting with the first non-zero digit and continue until the last non-zero digit;
  2. put the decimal point after the first digit;
  3. count how many digits the decimal point needs to move to get back to where it was originally (if there was no decimal point as the number was a whole number it was "hiding" after the ones-digit, the last digit);
  4. if the decimal point need to move left make this count negative;
  5. write ×10 to the power of this count after the number written in step 2.

→ 0.00450 = 4.5 × 10^-3
