This three page document are three handouts that I give to my students to study from and use as a reference.
Page 1. Rules of Integers. (Inc. how to add, subtract, multiply and signed numbers.)
Page 2 Rules for the 4 basic operations with regard to fractions and decimals. (This page is handwritten very neatly)
Page 3 Step by step instructions of how to convert between decimals, fractions and percents.
