Understanding Algebraic Expressions

The video tutorial reviews key algebraic vocabulary, including variables, constants, coefficients, and terms. It explains that 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?

• Symbols of addition

• Unknown quantities

• Known numbers

• Fixed values

In the example given, which letters are identified as variables?

• m and n

• x and y

• p and q

• a and b

What defines a constant in an algebraic expression?

• A number with a variable

• A multiplication symbol

• A number without a variable

• A symbol of addition

Which number is identified as a constant in the example?

• 5

• 3

• 2

• 8

What is a coefficient in an algebraic expression?

• A number divided by a variable

• A number added to a variable

• A number multiplied by a variable

• A number subtracted from a variable

In the example, which numbers are identified as coefficients?

• 5 and 3

• 8 and 2

• 6 and 7

• 1 and 4

How should coefficients and variables be written together?

• Separated by a multiplication symbol

• Coefficient first, then variable

• Variable first, then coefficient

• Separated by an addition symbol

What is a term in an algebraic expression?

• A number with a variable

• A multiplication symbol

• A part of the equation separated by addition or subtraction

• A constant value

Which of the following is NOT considered a term in the example?
