  2. Name- ________________________________ Warm-Up Checklist for Adding and Subtracting in Scientific notation • Always check to see if the exponents are the same when adding and subtracting in scientific notation. • If not, put into standard form. • Add or subtract the numbers. • Rewrite into scientific notation.

  3. 1. Same exponents Add Remember the mantissa has to be 1 or greater and less than 10. Final Answer

  4. 2. Different exponents Put in standard form and add. Rewrite in scientific notation.

  5. 3. Same exponents Subtract Remember the mantissa has to be 1 or greater and less than 10. Rewrite in scientific notation.
