This simple text makes basic quantum mechanics accessible with minimum mathematics. Assuming only algebra, but containing over 100 problems for the reader to do, it provides an easy way for the reader to learn part of the quantum language and use it to do problems. The focus is on the matrices representing physical quantities. States are described simply by mean values of physical quantities or by probabilities for possible values. This requires use of the algebra of matrices and complex numbers together with probabilities and mean values. These bits of mathematics are introduced at the beginning and then used over and over.
