What is scientific notation and why do we use it? This book will explain all this and show you how to convert back and forth between scientific notation and regular numbers, including negative exponents.
There are 20 books in the Pre-Algebra series. The first books continue from the Fraction series with more work on fractions and decimals. Books progress through percentages, proportions, metrics, scientific notation, order of operations and finally, probability in Book 20. Students who complete the Pre-Algebra series are now fully ready for Algebra (coming soon).
