Description
Book of ProofThis book is an introduction to the language and standard proof methods of mathematics. It is a bridge from the computational courses (such as calculus or differential equations) that students typically encounter in their first year of college to a more abstract outlook. It lays a foundation for more theoretical courses such as topology, analysis and abstract algebra. Author: Richard H. Hammack Publisher: Richard Hammack Published: 07 19 2019 Pages:

Great comfortable, pillows.
Color: Black(4pack), Size: Standard
These are some great, comfortable pillows. They are soft and feel great. They are good for sleeping on or just using them to be comfortable in bed.

The Perfect Pillow
Size: Queen (Low Loft)
Finally found the right pillow for me. I have purchased quite a few latex pillows attempting to find the right one. I was apprehensive due to the support description being "extra soft". Yes, it's super soft when you pick it up and squeeze it, but it provides the perfect amount of support for side and back sleeping.

Absolutely awesome pillow! My sister and I used to have pillows like these as kids and always look to replace them. These are wonderful. Cool and comfortable and the perfect amount of firm and support . Spouses fight us for them!!

Nice foam latex pillow. A little thicker than I wanted, but has improved my sleep quality
