What should you do if you doubt your standard form calculation?

• Ask a friend

• Use a calculator

• Convert it to an ordinary number and back

• Leave it as it is

What is the final step after performing a calculation in standard form?

• Add the indices

• Multiply the coefficients

• Check if the coefficient is between 1 and 10

• Subtract the indices

What is the key takeaway for adding and subtracting in standard form?

• Use indices rules

• Convert to ordinary numbers first

• Always multiply the coefficients

• Divide the indices
