Multiplying and dividing significant figures | Science Toolkit | Khan Academy

Courses on Khan Academy are always 100% free. Start practicing—and saving your progress—now! For multiplication and division, the final answer must match the measurement with the fewest significant figures. This is different from addition and subtraction, which use decimal places. After calculating the answer, round it to the correct number of significant figures. When rounding, dropped digits to the left of the decimal are replaced with zeros if needed. ------------------ Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
