Simplifying Expressions with Order of Operations

This video tutorial introduces the concept of simplifying expressions using the order of operations, commonly known as PEMDAS. It explains the importance of handling parentheses and brackets first and provides step-by-step examples to demonstrate the process. The tutorial includes practice problems for viewers to solve, reinforcing the concepts taught.

What does PEMDAS stand for?

• Parentheses, Exponents, More Division, Addition, Subtraction

• Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

In the order of operations, which comes first?

• Addition

• Subtraction

• Multiplication

• Parentheses

In expressions, multiplication and division are treated as:

• Identical operations

• Inverse operations

• Unrelated operations

• Sequential operations

What is the result of simplifying the expression 3 * (8 - 4) * 18?

• 216

• 144

• 48

• 72

How do you approach an expression with both parentheses and brackets?

• Solve both at the same time

• Ignore both and simplify the rest

• Solve parentheses first

• Solve brackets first

If you have a 3 next to a bracket without an operation sign, what operation does it imply?

• Division

• Multiplication

• Subtraction

• Addition

• 7

• 14

• 21

• 28

What does it mean when numbers are adjacent to parentheses or brackets?

• Subtraction

• Multiplication

• Division

• Addition

When simplifying expressions, what should you do if you encounter multiple sets of parentheses?

• Choose any set to solve first

• Solve from the innermost set outwards

• Ignore all but the outermost set

• Solve from the outermost set inwards

What is the final result of simplifying the expression with nested parentheses and brackets: 18 + [50 / (5 * 5)]?

• 20
