When multiplying numbers in scientific notation, what do you do with the exponents?

• Multiply them

• Add them

• Keep them the same

• Make them equal

What is the ONLY thing that matters when adding and subtracting numbers in scientific notation?

• That the exponents are different

• That the constants are the same

• That the exponents are the same

• That both constants are positive

When adding and subtracting in scientific notation, what do you do with the constants?

• Make them the same

• Add/subtract them

• Keep them

• Multiply/divide them

In what types of problems do you have to make sure the exponents are the same before beginning to compute?
