Description
Problem Solving Through Recreational MathematicsHistorically, many of the most important mathematical concepts arose from problems that were recreational in origin. This book takes advantage of that fact, using recreational mathematics problems, puzzles and games to teach students how to think critically. Encouraging active participation rather than just observation, the book focuses less on mathematical results than on how these results can be applied to thinking about problems and solving them.
Historically, many of the most important mathematical concepts arose from problems that were recreational in origin. This book takes advantage of that fact, using recreational mathematics -- problems, puzzles and games -- to teach students how to think critically. Encouraging active participation rather than just observation, the book focuses less on mathematical results than on how these results can be applied to thinking about problems and solving them.Each chapter contains a diverse array of problems in such areas as logic, number and graph theory, two-player games of strategy, solitaire games and puzzles, and much more. Sample problems (solved in the text) whet readers' appetites and motivate discussions; practice problems solidify their grasp of mathematical ideas; and exercises challenge them, fostering problem-solving ability. Appendixes contain information on basic algebraic techniques and mathematical inductions, and other helpful addenda include hints and solutions, plus answers to selected problems. An extensive appendix on probability is new to this Dover edition. Free solutions manual available for download at the Dover website.

Every bit as good as OEM.
Size: 2023-26 CRV 1.5L Gas, Size: 2023-26 CRV 1.5L Gas
These fit my wife's 2026 CRV perfectly.
Replacement: No issues whatsoever with installing the cabin or engine air filter and all-told it took all of 5 minutes to replace both filters. Getting to the engine air filter took longer than replacing it.
Quality / durability: These filters are every bit as durable and high quality as the OEM filters I replaced them with. When I took each filter out I inspected it to make sure that they were comparable and was pleasantly surprised that there was virtually no difference between the two in construction or the appearance of the membrane.
Airflow: The membranes looked nearly identical when held to the light so airflow should be just as good with these new replacement filters as it was with the OEM. I can't believe how good of a value these filters are.

Perfect fit
Size: 2023-26 CRV 1.5L Gas
This filter set was a perfect fit for my vehicle and installed without any issues. Everything lined up exactly as expected, which made the replacement quick and straightforward.
The quality feels comparable to the original filters, and it is a great option if you are looking for a direct replacement without overpaying at the dealership.
Overall, this is a reliable and easy upgrade for routine maintenance. I would use this again.

Save money, buy non oem
Size: 2023-26 CRV 1.5L Gas
This Engine Cabin Air Filter Set is designed specifically for Honda CRV 1.5L Gas models from 2023 through 2026 and Honda Civic 1.5L Gas models from 2022 through 2026. It is important to note that this filter set does NOT fit the 2.0L engine variants. The filters replace the OEM part numbers 17220-64A-A00 and 80291-T5R-A01, ensuring a proper fit and function.
That being said, however, the AIR FILTER does fit the 2017-2021 CRV

Same quality as oem
Size: 2023-26 CRV 1.5L Gas
This is same quality as oem. Very much similar. The only difference is that this cabin filter has activated carbon which reduces the cabin unpleasant odor. Very easy to install. The price is affordable. I save money on this doing DIY.
