🎯 What You'll Learn

Learning Objectives

1

Understand how parentheses change the order of mathematical operations

2

Evaluate mathematical expressions with parentheses correctly

3

Recognize God's love for order and precision

📖 Scripture Connection

1 Corinthians 14:40

“Let all things be done decently and in order.”

— 1 Corinthians 14:40 (WEB)

Just as parentheses bring order to mathematical expressions, God values orderliness in our lives
