Summary of multiplying by any digit - The fastest way to do math

The video tutorial introduces the Tranberg system for speed multiplication, providing a summary of rules for multiplying by single digits. It emphasizes the importance of practice to internalize these rules, similar to learning times tables. The tutorial explains the setup of the Tranberg system, including the use of a 'neighbor' concept and carrying over numbers. It concludes with tips for applying the rules effectively and highlights the significance of practicing to achieve speed and accuracy in multiplication.

What is the primary goal of practicing the rules in the Tranberg system?

• To learn new mathematical concepts

• To avoid using calculators

• To improve speed and accuracy

• To memorize the times tables

When multiplying by 11 using the Tranberg system, what should you do?

• Add five if the number is odd

• Add the neighbor

• Subtract from 10

• Double the number

What is the rule for multiplying by 9 in the Tranberg system?

• Subtract from 10 and double

• Use half the neighbor plus five

• Add the neighbor

• Subtract from 9 and add the neighbor

Why is a zero placed in front of numbers in the Tranberg system?

• To simplify subtraction

• To avoid errors

• To use the first number as a neighbor

• To make calculations easier

What should you do if a calculated number is larger than 10 in the Tranberg system?

• Carry over the extra digit

• Subtract 10 from it

• Add it to the next number

• Ignore the extra digit

What is the first step when using the Tranberg system to avoid forgetting carried numbers?

• Subtract from 10 first

• Double the numbers first

• Add the fives first

• Add the carries first

How can you achieve speed in the Tranberg system?

• By writing down all steps

• By using a calculator

• By practicing regularly

• By memorizing all rules
