Knowledge of the following mathematical operations is required for STAT 200:

• Addition
• Subtraction
• Division
• Multiplication
• Radicals (square roots)
• Exponents
• Summations  \(\left( \sum \right) \)
• Basic linear equations (i.e., \(y=mx+b\))

The ability to perform these operations in the appropriate order is necessary. The following sections will review order of operations, summations, and basic linear equations.

In the past, students without knowledge of these topics have struggled to be successful in STAT 200. If you have any questions about these mathematical operations after reviewing these materials, please contact your instructor as soon as possible. We want our students to be successful!
