Linear algebra is about solving systems of linear equations. The Linear Algebra book helps students master a standard undergraduate linear algebra course — Gaussian reduction, vector spaces, linear maps, determinants, and eigenvalues and eigenvectors — using a developmental approach in which results are proved rather than merely presented.
In Food Alphabet children get an introduction to the different types of foods that they may or may not be familiar with so that they can become familiar with the letters of the alphabet.


Guacamole is a spicy Mexican paste made from crushed avocado and various seasonings, usually including onions, peppers, garlic and tomatoes. Guacamole is used as a condiment, an ingredient, and as an appetizer when served with tortilla chips.
