Understanding Algebraic Expressions

The video tutorial reviews key algebraic vocabulary, including variables, constants, coefficients, and terms. Variables are unknowns in expressions, constants are numbers without variables, coefficients are numbers multiplied by variables, and terms are parts of equations separated by addition or subtraction symbols. The tutorial emphasizes the importance of understanding these concepts for solving algebraic problems.

Which of the following is NOT a key algebraic term introduced in the video?

• Coefficient

• Variable

• Equation

• Constant

What are variables in an algebraic expression?

• Known numbers

• Unknown quantities

• Fixed values

• Mathematical operations

In the expression 5x + 3y, which are the variables?

• 5 and 3

• None of the above

• 5x and 3y

• x and y

What defines a constant in an algebraic expression?

• A number without a variable

• A variable without a number

• A symbol of addition

• A number with a variable

In the expression 5x + 8, what is the constant?

• 8

• x

• 5

• 5x

What is a coefficient in an algebraic expression?

• A number added to a variable

• A number multiplied by a variable

• A variable without a number

• A constant value

In the expression 3y, what is the coefficient?

• None of the above

• 3

• 3y

• y

How should coefficients and variables be written in an expression?

• Separated by a multiplication symbol

• Separated by an addition symbol

• Variable first, then coefficient

• Coefficient first, then variable

What is a term in an algebraic expression?

• A variable without a number

• A symbol of multiplication

• A number without a variable

• A part of the expression separated by addition or subtraction

In the expression 5x + 3y + 8, how many terms are there?

• 1

• 2

• 3

• 4
