What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 3 multiplied by 4 (3 x 4) means adding 3 four times (3 + 3 + 3 + 3) which equals 12.

How do you calculate the total number of pages printed if a business prints a certain number of books with a specific number of pages?

Back

To find the total number of pages printed, multiply the number of books by the number of pages in each book. For example, if 624 books are printed with 95 pages each, the total pages printed is 624 x 95 = 59,280.

Front

What is division?

Back

Division is a mathematical operation that splits a number into equal parts. For example, if you have 672 seats and want to find out how many rows of 12 seats there are, you divide 672 by 12, which equals 56.

How do you find the cost of multiple items if you know the cost of one item?

Back

To find the total cost of multiple items, multiply the cost of one item by the number of items. For example, if one pack of gum costs $1.27 and you want to buy 58 packs, the total cost is $1.27 x 58 = $73.66.

Front

What is the formula to find the total number of items if each item has a specific quantity?

Back

To find the total number of items, multiply the number of items by the quantity each item has. For example, if there are 152 students and each has 18 pencils, the total number of pencils is 152 x 18 = 2,736.

What is a gallon in terms of distance traveled by a car?

Back

A gallon is a unit of measurement for liquid capacity. In the context of a car, it represents how far the car can travel per gallon of gas. For example, if a car travels 26 miles per gallon, it means it can go 26 miles using one gallon of gas.

Front

How do you calculate the number of gallons used based on miles driven and miles per gallon?

Back

To calculate the number of gallons used, divide the total miles driven by the miles per gallon. For example, if Mrs. Renning drove 3,718 miles and her car uses 1 gallon for every 26 miles, the gallons used is 3,718 ÷ 26 = 143.

Front

What is the importance of understanding multiplication in real-life situations?

Back

Understanding multiplication helps in solving problems related to groups of items, such as calculating total costs, quantities, and measurements in everyday life.

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. If you know that 4 x 3 = 12, you can also say that 12 ÷ 4 = 3.

Front

How can you check if your multiplication answer is correct?

Back

You can check your multiplication answer by using division. If you multiplied 3 x 4 to get 12, you can divide 12 by 3 to see if you get back to 4.
