Operations on whole numbers

What is an example of a multiplication word problem?

• If there are 4 bags with 6 apples in each bag, how many apples are there in total? (4 x 6 = 24 apples)

• A farmer has 5 fields, and each field has 10 rows of corn. How many rows of corn are there in total? (5 x 10 = 50 rows)

• If a car travels 60 miles per hour for 2 hours, how far does it travel? (60 x 2 = 120 miles)

• A baker makes 3 dozen cookies, and each dozen has 12 cookies. How many cookies does the baker make in total? (3 x 12 = 36 cookies)

What is multiplication?

• A mathematical operation that represents the repeated addition of a number.

• A method of dividing numbers into equal parts.

• A technique for finding the square root of a number.

• A process of calculating the average of a set of numbers.

What is the identity property of multiplication?

• Any number multiplied by 0 remains the same.

• Any number multiplied by 1 remains the same.

• Any number multiplied by itself remains the same.

• Any number multiplied by 2 remains the same.

What is the commutative property of multiplication?

• The commutative property states that changing the order of the numbers in a multiplication problem does not change the product.

• The commutative property states that the product of two numbers is always greater than either number.

• The commutative property states that multiplication can only be performed on whole numbers.

• The commutative property states that the product of two numbers is the same as their sum.

How can you check if your multiplication is correct?

• By using subtraction

• By using addition (repeated addition)

• By using multiplication again

• By using the inverse operation, which is subtraction

What is the associative property of multiplication?

• The associative property states that the product of two numbers is always the same regardless of the order in which they are multiplied.

• The associative property states that when multiplying three or more numbers, the way in which the numbers are grouped does not change the product. For example, (2 x 3) x 4 = 2 x (3 x 4).

• The associative property states that the sum of two numbers is always the same regardless of the order in which they are added.

• The associative property states that when adding three or more numbers, the way in which the numbers are grouped does not change the sum.
