Multiply three or more numbers: word problems

Learning Objectives Identify the key information and numbers in word problems involving multiplication. Determine when a word problem requires multiplying three or more numbers. Apply the associative property of multiplication to group numbers for easier calculation. Solve multi-step word problems by multiplying three or more whole numbers. Interpret the product in the context of the word problem. Formulate a multiplication equation to represent a given word problem. Ever wonder how many cookies you'd need for a huge party if each guest eats a certain number, and you have many trays? 🍪 Let's find out how to multiply more than two numbers to solve real-life puzzles! In this lesson, you'll learn how to tackle word problems that require multiplying three or mor...

TermDefinitionExample FactorA number that is multiplied by another number to find a product.In $2 \times 3 \times 4 = 24$, the numbers 2, 3, and 4 are factors. ProductThe result of multiplication.In $2 \times 3 \times 4 = 24$, the number 24 is the product. Word ProblemA mathematical problem presented in a story or real-life context, requiring you to read and understand the situation.If a baker makes 3 batches of cookies, with 4 rows in each batch, and 5 cookies in each row, how many cookies are there? Associative Property of MultiplicationThe way factors are grouped in a multiplication problem does not change the product.$(2 \times 3) \times 4 = 6 \times 4 = 24$ is the same as $2 \times (3 \times 4) = 2 \times 12 = 24$. Commutative Property of MultiplicationThe order of factors in a multi...

Associative Property of Multiplication $(a \times b) \times c = a \times (b \times c)$ This rule allows you to group numbers in any way when multiplying three or more numbers. You can multiply any two numbers first, then multiply that result by the next number. This can make calculations easier, especially for mental math. Commutative Property of Multiplication $a \times b \times c = c \times a \times b$ This rule means you can multiply numbers in any order without changing the final product. You can rearrange the factors to make the multiplication simpler or to group numbers that are easier to multiply together. General Multiplication Rule for Multiple Factors To find the product of three or more numbers, multiply any two numbers first, then multiply that result by th...
