Simplifying Expressions and Distributive Property

The video tutorial guides students through a grade six math practice test question, focusing on simplifying expressions and identifying equivalent expressions. It emphasizes the importance of understanding like terms, the order of operations, and the correct use of exponents. The tutorial also warns against common mistakes, such as misinterpreting exponents and failing to simplify expressions fully. By following the steps outlined, students can effectively solve the problem and avoid errors.

What is the main focus of the grade six math practice test?

• To solve complex algebraic equations

• To practice multiplication tables

• To select two equivalent expressions

• To learn about geometry

Why is it important to select two answers in the test?

• Because it increases your score

• Because it is a trick question

• Because it helps in understanding the concept better

• Because the test requires two answers for full credit

What is the first step in simplifying the expression 4 + W + 12W?

• Combine like terms W and 12W

• Multiply all terms

• Subtract 4 from W

• Add 4 and W

Why can't you combine 4 with W in the expression 4 + W + 12W?

• Because they are both variables

• Because 4 is a constant and W is a variable

• Because they are both constants

• Because 4 is larger than W

What mistake should you avoid when simplifying expressions?

• Ignoring the constant term

• Multiplying instead of adding

• Forgetting to add coefficients

• Combining unlike terms

What is the correct simplified form of 4 + W + 12W?

• 4 + 13W

• 16W

• 4W + 12

• W + 12W

Why is W squared not a correct simplification of W + 12W?

• Because you cannot change exponents by adding

• Because it requires division

• Because it is not a like term

• Because W squared is a different variable

What operation allows you to change the exponent of a variable?

• Division

• Multiplication

• Subtraction

• Addition

What should you do when you see an expression with W squared in a multiple-choice question?

• Ignore it as it is incorrect

• Select it as the correct answer

• Add it to the constant term

• Multiply it by another term

What is the first step in the order of operations?

• Multiplication

• Addition

• Parentheses

• Exponents
