I think you need to count to 20 by a number line.

First, find a two digit number for example my number will be 14. Next, count by 20s on a number line 14 times until you get an answer. Your final answer shuld be 280.

well, multiplying by 20 means adding it up 20 times.

I assume you know how to add on the number line.

Did you know?

Did you know that you can use a number line to multiply a 2-digit number by 20? Here's how: 1. Draw a number line with equally spaced ticks, starting from 0 and ending at your 2-digit number. 2. Identify the tens and ones place digits of the 2-digit number. Let's take an example: 42 (4 in the tens place and 2 in the ones place). 3. Multiply the tens place digit by 20. In our example, 4 x 20 = 80. 4. Starting from 0 on the number line, jump forward by that product (80 in this case). Mark the spot with an arrow or dot. 5. Now, multiply the ones place digit by 20. In our example, 2 x 20 = 40. 6. Starting from the marked spot, jump forward by that second product (40 in this case). Mark the new spot with another arrow or dot. 7. The final spot on the number line will give you the answer. In our example, the final spot will be at 120. Using this method, you can easily multiply any 2-digit number by 20 using a number line. Give it a try with different numbers and test your multiplication skills!
