Word Problems-Detailed Explanations of Reasoning and Solving Strategies: Volume 2 Answer Key

This is the answer key of Volume 2 of the entire set of 12 volumes of word problems solving strategies. If you want to set a solid foundation in math, grasping the techniques on solving word problems is the key to it. This set of books teaches you the techniques and strategies you need to solve word problems. Sample question in this volume: Mom is 36 years old. If Lily is 12 years old, how much older is Mom than Lily? Reasoning and solution: Each year in Mom's age finds a match from the years of Lily's age so some years in Mom's age do not have any matches. How many years in Mom's age do not have any matches? The 12 years that have found matches leave the group of 36 years so we subtract 12 years from 36 years s to find how many years do not have any matches: 36-12=24 years Mom is 24 years older than Lily. The techniques on using the "than" method to solve problems with " more than or less than" in them, on using "matching games" to solve word problems with " how much more or how much less" in them, on using "combining" to do addition and on using "leaving a group" to subtract are covered in this volume. There is more in the volume than what is mentioned. Detailed explanations of the reasoning and solving strategies for each and every problem in Volume 2 are given in this book.
