Key Insights

  • 🫥 The line technique for multiplication involves drawing lines for each digit and counting intersections in each zone.
  • 💦 This method works well for numbers with digits less than 5 and provides a quick and visual way to perform multiplication.
  • 🫥 However, for numbers with digits 5 or greater, the line technique becomes messy and tedious.
  • 🫥 The line technique can be used for numbers with more than two digits by following the same approach of drawing lines and counting intersections.
  • 🫥 If the line technique does not work, alternative methods such as traditional multiplication or using a calculator can be used.
  • 🫥 The line technique offers a simplified and visual approach to multiplication, making it accessible for learners of different skill levels.
  • 🫥 Practice and familiarity with the line technique can build confidence in using it for various multiplication problems.

Transcript

we have been asked to multiply 41 with 13 using lines we have already seen how this technique works for the digit 1 we draw one line for the digit 2 we draw two lines and so on the first digit of the number 41 is 4 so we draw four lines and for the second digit one we draw one line after leaving some space for 13 we draw one line for one and three ...

Questions & Answers

Q: How do you multiply 41 with 13 using the line technique?

To multiply 41 with 13 using the line technique, draw four lines for 4 and one line for 1. Count the intersections in each zone, and add the carried over values to get the final answer of 533.

Q: Can this line technique be used for numbers with more than two digits?

Yes, the line technique can be used for numbers with more than two digits. Simply draw the appropriate number of lines for each digit and count the intersections in each zone to get the result.

Q: Why does the line technique not work for numbers with digits 5 or greater?

The line technique becomes messy and tedious for numbers with digits 5 or greater. The method of counting intersections becomes cluttered, making it difficult to accurately determine the product.

Q: Is there an alternative method to use if the line technique does not work?

Yes, if the line technique does not work or becomes too messy, there are alternative multiplication methods available. These methods, such as traditional multiplication or using a calculator, can be used to solve multiplication problems with numbers containing digits 5 or greater.

Summary & Key Takeaways

  • Multiply 41 with 13 using lines and counting intersections. Start by drawing four lines for 4, and one line for 1. Count the intersections in each zone to get the answer of 533.

  • Multiply 211 with 32 using the same technique. Draw two lines for 2, one line for 1, and one line for 1. Count the intersections in each zone to get the answer of 6752.

  • This method may not work for numbers with digits 5 or greater, as it becomes messy. An alternative method will be covered in the next part.
