4.NBT.5 Multiplication Review

What is multiplication?

• A mathematical operation that represents the process of adding a number to itself a certain number of times.

• A method of dividing numbers into equal parts.

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

• A way to calculate the average of a set of numbers.

What is the associative property of multiplication?

• The associative property of multiplication states that the way in which numbers are grouped in multiplication does not change the product.

• The associative property of multiplication states that the order of numbers in multiplication does not change the product.

• The associative property of multiplication states that multiplying a number by zero results in zero.

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

What is the significance of zero in multiplication?

• Any number multiplied by zero equals zero.

• Zero is the identity element in multiplication.

• Zero can be multiplied by any number to get one.

• Multiplying by zero increases the value of the number.

What is a factor in multiplication?

• A number that is added to another number to get a sum.

• A number that is multiplied by another number to get a product.

• A number that is divided by another number to get a quotient.

• A number that is subtracted from another number to get a difference.

How do you multiply a two-digit number by a one-digit number?

• You can use the distributive property, breaking the two-digit number into tens and ones, multiplying each part by the one-digit number, and then adding the results.

• Simply multiply the two-digit number by the one-digit number directly without any breakdown.

• Add the two digits of the two-digit number and then multiply the sum by the one-digit number.

• Multiply the one-digit number by the first digit of the two-digit number only.

What is the product in multiplication?

• The sum of two or more numbers.

• The result of multiplying two or more numbers together.

• The difference between two numbers.

• The average of two or more numbers.

How do you represent multiplication in mathematical notation?

• '+' symbol

• '×' or '*' symbol

• '/' symbol

• '-' symbol

What is the commutative property of multiplication?

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

• The commutative property of multiplication states that changing the order of the numbers being multiplied does not change the product.

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

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

What is an area model in multiplication?

• A method of multiplication that uses addition instead of multiplication.

• A visual representation of multiplication that uses rectangles to show how two numbers can be multiplied together by dividing them into parts.

• A technique that involves multiplying numbers using a number line.

• A formula used to calculate the area of a rectangle.

How can you use estimation in multiplication?

• By rounding numbers to make calculations easier and quicker, allowing you to get a rough idea of the product.

• By using exact values to ensure precision in the product.

• By multiplying the numbers without any adjustments or rounding.

• By applying complex formulas to derive the product.
