Some students believe that when adding numbers in scientific notation, you can always add the first factors and the exponents. Do you agree or disagree? Use examples and reasoning to support your answer.
Disagree. When adding numbers in scientific notation, you can only add the first factors if the exponents are the same. But must be rewritten so both numbers have the same exponent before adding. Adding exponents is only for multiplication, not addition.
