Arithmetical Reasoning Study Materials:

This section provides an overview of the basic arithmetic concepts and calculations found in problems associated with organizational practices in New York State. While most of the concepts will be familiar, some of them will be new or are items you have not seen for a long time. This guide is meant as a refresher and tool to support the mental processes used in arithmetic problem solving. This information has been condensed to
closely resemble the language used on the Civil Service Test. Additional practice questions are provided in a supplement to this guide.

Integers can be:
 Added (1) + (-2) + (2)= 1
 Subtracted (2) – (12) = -10
 Multiplied (-2) x (4) = -8
 Divided (10) ÷ (2) = 5
