TermDefinitionExample ProductThe result obtained when two or more numbers are multiplied together.In $2 \times 3 \times 4 = 24$, the number 24 is the product. FactorA number that is multiplied by another number to get a product.In $2 \times 3 \times 4 = 24$, the numbers 2, 3, and 4 are factors. Word ProblemA mathematical problem presented in a story or real-world context, requiring you to identify the numbers and operations needed to solve it.If there are 3 rows of 5 chairs, and 2 such sections, how many chairs total? Associative Property of MultiplicationThis property states that when multiplying three or more numbers, the way the factors are grouped does not change the product.$(2 \times 3) \times 4 = 6 \times 4 = 24$, and $2 \times (3 \times 4) = 2 \times 12 = 24$. Both give the same p...

Associative Property of Multiplication $(a \times b) \times c = a \times (b \times c)$ This rule tells us that when you multiply three or more numbers, you can group them in any way you choose, and the final product will always be the same. This can be very helpful for simplifying calculations or making them easier to do mentally. Strategy for Solving Word Problems Read $\rightarrow$ Plan $\rightarrow$ Solve $\rightarrow$ Check 1. **Read**: Understand the problem, identify knowns and unknowns. 2. **Plan**: Decide which operations are needed and in what order. 3. **Solve**: Perform the calculations. 4. **Check**: Review your answer for reasonableness and accuracy, and make sure it answers the original question. Multiplication of Multiple Factors $a \times b \times c \ti...
