Exploring Algebraic Expressions with Tables

The video tutorial explains how algebraic expressions can represent data in tables. It covers both additive and multiplicative relationships, showing how to identify and express these relationships algebraically. The tutorial also emphasizes the importance of understanding the direction of operations and the correct format for writing algebraic expressions.

What are the two types of relationships you can identify in a table?

• Multiplicative and Additive

• Additive and Divisive

• Subtractive and Divisive

• Multiplicative and Subtractive

If you have a table where 1 becomes 10, which of the following is a possible multiplicative relationship?

• 1 / 10

• 1 * 10

• 1 - 9

• 1 + 9

In the example where 2 becomes 11, which relationship is correct?

• 2 * 10

• 2 + 9

• 2 - 9

• 2 / 10

What should you do if a table goes from right to left?

• Use the same operation

• Multiply by 2

• Use the opposite operation

• Ignore the direction

How are variables typically defined in a table?

• Randomly

• By the table headers

• By the teacher

• By the user

What is the algebraic expression for hours plus 9?

• H * 9

• H + 9

• H - 9

• H / 9

In an additive relationship, what must be included in your answer?

• Units

• Dollar signs

• Multiplication symbols

• Division symbols

If an alien has 8 legs, what is the multiplicative relationship for 2 aliens?

• 2 + 8

• 2 * 8

• 2 / 8

• 2 - 8

Which of the following is the correct way to write a multiplication expression in algebra?

• X*8

• 8*X

• X8

• 8X

Why should the numeric coefficient come before the variable in a multiplication expression?

• Because it looks better

• Because numbers are more important

• Because letters are more important

• Because it is easier to read
