This video tutorial teaches how to write multi-step algebraic expressions using real-world scenarios. It emphasizes defining variables, identifying operations, and understanding the impact of variable values on expressions. A practical example involving cupcakes illustrates the process of forming and evaluating expressions. The tutorial also addresses common misunderstandings, such as writing expressions word for word, and highlights the importance of operation order in subtraction.

What is the first step in writing an algebraic expression?

• Determine the operation

• Solve the expression

• Define the variable

• Write the expression word for word

In the expression 2c - 6, what does the '2' represent?

• Doubling the number of cupcakes

• Dividing the cupcakes by 2

• Adding 2 cupcakes

• Subtracting 2 cupcakes

If Marissa made 5 cupcakes, how many did Sandra make according to the expression 2c - 6?

• 5 cupcakes

• 10 cupcakes

• 2 cupcakes

• 4 cupcakes

Why is it incorrect to write expressions word for word?

• It leads to incorrect order of operations

• It makes the expression too long

• It simplifies the expression too much

• It is difficult to understand

What is a common mistake when writing expressions involving subtraction?

• Forgetting to define the variable

• Using addition instead of subtraction

• Writing the operations in the wrong order

• Multiplying instead of dividing
