LESSON 1 -2 Order of Operations

GOALS Evaluate numerical expressions by using the order of operations. Evaluate algebraic expressions by using the order of operations.

VOCABULARY Evaluate an expression means to find its value Order of operations are rules to let you know which operation to perform first 1. Evaluate expressions inside grouping symbols 2. Evaluate all powers and roots 3. Multiply and/or divide from left to right 4. Add and/or subtract from left to right P E M D A S

EVALUATE NUMERICAL EXPRESSIONS

USE ORDER OF OPERATIONS

EXPRESSIONS WITH GROUPING SYMBOLS

EVALUATE AN ALGEBRAIC EXPRESSION

REAL-WORLD EXAMPLE: WRITE AND EVALUATE AN EXPRESSION Find the area of a triangle with a base of 123 feet and a height of 62 feet. Start with the formula for the area of a triangle

REAL-WORLD EXAMPLE: WRITE AND EVALUATE AN EXPRESSION ARCHITECTURE Each side of the Great Pyramid at Giza, Egypt, is a triangle. The base of each triangle once measured 230 meters. The height of each triangle once measured 187 meters. The area of a triangle is one-half the product of the base b and its height h
