Combining Like Terms with Positive Numbers

What are 'like terms' in an algebraic expression?

• Terms that have different coefficients

• Terms that are multiplied together

• Terms that have the same variable raised to the same power

• Terms that are separated by a plus or minus sign

What does it mean to simplify an expression?

• To reduce the expression to the lowest number of terms

• To increase the number of terms

• To write it in its longest possible form

• To change the variables in the expression

What is the coefficient of a variable if it is not explicitly shown?

• 1

• The variable itself

• 0

• 10

How do you simplify the expression y + y + y + y?

• y*y

• y^4

• 4y

• 2y

If you have the terms 3x and 5x, how would you combine them?

• 3x + 5x

• 8x

• 15x

• 2x

In the expression 3x + 2x, what is the simplified form?

• 5x

• 5

• 6x

• x

What is the result of repeatedly multiplying 1 by itself four times?

• 1

• 4

• 0

• 1^4

In the expression 3b + b, what is the simplified form?

• 3b + b

• 2b

• 4b

• 3b^2

What does the expression 5 + 2 simplify to?

• 5

• 3

• 7

• 10

If an expression includes b^2 and b, can these terms be combined?

• Yes, as they are both terms of b

• No, because they have different powers

• Yes, if you multiply them

• No, unless you change the expression
