Adding Subtracting Multiplying Exponents

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

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

• Keep them

• Add them

• Multiply them
