Order of Operations and Basic Arithmetic

The video tutorial explains how to simplify a mathematical expression using the order of operations. It begins by addressing the importance of simplifying within parentheses, focusing on multiplication before subtraction. The tutorial then proceeds to simplify the expression step-by-step, ultimately arriving at the final result. The process is verified using a graphing calculator to ensure accuracy.

What is the first step in the order of operations?

• Subtract numbers

• Addition

• Subtraction

• Multiplication

What is the result of multiplying 9 by 7?

• 56

• 63

• 72

• 81

After simplifying the multiplication inside the parentheses, what is the next operation to perform?

• Subtraction

• Exponentiation

• Addition

• Division

What is the result of subtracting 42 from 63?

• 19

• 21

What operation is skipped because there are no exponents in the expression?

• Exponentiation

• Addition

• Subtraction

• Multiplication

What is the result of multiplying 4 by 21?

• 64

• 84

• 74

• 94

What is the final result of the expression 95 - 84?

• 9

• 12

• 10
