How do you calculate the total number of items sold when given multiple containers of different sizes?

Back

To calculate the total number of items sold, multiply the number of containers by the number of items in each container and then sum the results. For example, if there are 3 containers of 24 cookies and 3 containers of 48 cookies, the total is (3 x 24) + (3 x 48) = 72 + 144 = 216 cookies.

What is a partial product in multiplication?

Back

A partial product is the result of multiplying a single digit of one factor by the entire other factor in a multiplication problem. For example, in 125 x 7, the partial products would be 700 (7 x 100), 140 (7 x 20), and 35 (7 x 5).

How do you find the total when given a repeated measurement, such as distance?

Back

To find the total distance when given a repeated measurement, multiply the distance by the number of times it is repeated. For example, if a soccer field is 110 meters long and Messi ran it 8 times, the total distance is 110 x 8 = 880 meters.

How do you determine the total capacity of a parking garage with multiple floors?

Back

To determine the total capacity of a parking garage, multiply the number of floors by the number of cars that can be parked on each floor. For example, if there are 7 floors and each can hold 125 cars, the total capacity is 7 x 125 = 875 cars.

Front

What is the process for solving word problems involving multiplication?

Back

Front

How can you break down a multiplication problem into simpler parts?

Back

You can break down a multiplication problem into simpler parts by using the distributive property, which allows you to multiply each part of one factor by the other factor and then add the results.

Front

What is the relationship between multiplication and addition?

Back

Multiplication is a form of repeated addition. For example, 4 x 3 can be thought of as adding 3 four times (3 + 3 + 3 + 3).
