3.03 Larger multiplications

Lesson

Are you ready?

Do you remember how to use the standard algorithm to multiply large numbers together? Let's try this problem to practice.

Find $296\times13$296×13.

Vocabulary:
  • You might notice that sometimes the standard algorithm is called the 'vertical algorithm'. Let's think about why. When we use the standard algorithm, we line our numbers up in 'vertical' place value columns.

This video helps us review how we can relate the area model to the standard algorithm for multiplication.

 

Apply

Question

Find $3346\times22$3346×22.

 

Remember!

The standard algorithm uses the same processes, no matter how large our numbers are. We just need to remember that we write the results of the multiplications with the correct place values.
