• At the end of the article there are typical ones ask with answers.

In elementary school - especially in grades 1 and 2 - arithmetic is learned in the number range up to 10 and up to 20. This is exactly what we will take a closer look at in the next few sections. We also offer similar articles on this website: Neighboring numbers class 1 and 2 or counting forwards and backwards.

In order to solve plus problems in the number range up to 10 or in the number range up to 20, one must first of all know these numbers. It is therefore important for students to learn the numbers from 1 to 20 by heart and to be able to count them:

• 1 one
• 2 - two
• 3 three
• 4 - four
• 5 - five
• 6 - six
• 7 - seven
• 8 - eight
• 9 - nine
• 10 - ten
• 11 - eleven
• 12 - twelve
• 13 - thirteen
• 14 - fourteen
• 15 - fifteen
• 16 - sixteen
• 17 - seventeen
• 18 - eighteen
• 19 - nineteen
• 20 - twenty

We just looked at the numbers from 1 to 20. As I said: everyone should know these numbers by heart and be able to count them up and down. For plus and minus tasks, it is important to master this.

Let's come to examples of plus and minus tasks. Let's start with plus tasks. As a first example, we will look at the number range up to 10 with explanations.

Examples 1:

• 2 + 1 = 3, because if I go from the 2 by 1 I land on the 3.
• 3 + 1 = 4, because if I go from 3 by 1 I land on 4.
• 4 + 2 = 6, because if I go from 4 to 2 I land on 6.
• 3 + 3 = 6, because if I go from 3 by 3 I land on 6.
• 4 + 3 = 7, because if I go from 4 to 3 I land on 7.
• 7 + 2 = 9, because if I go from 7 to 2 I land on 9.

The next section deals with plus problems in the number range up to 20.

Examples 2:

• 6 + 5 = 11, because if I go from 6 to 5 I end up on 11.
• 7 + 4 = 11, because if I go from 7 to 4 I end up on 11.
• 8 + 4 = 12, because if I go from 8 to 4 I land on 12.
• 10 + 4 = 14, because if I go on the 10 by 4 I land on the 14.
• 11 + 5 = 16, because if I go from 11 to 5 I end up on 16.
• 15 + 3 = 18, because if I go from 15 to 3 I land on 18.

The next section deals with negative problems in the number range up to 10.

Example 3:

• 7 - 1 = 6, because if I go back from 7 by 1, I land on 6.
• 8 - 3 = 5, because if I go back from 8 by 3 I land on 5.
• 9 - 7 = 2, because if I go back from 9 at 7 I land on 2.
• 3 - 2 = 1, because if I go back from the 3 by 2, I land on the 1.
• 4 - 2 = 2, because if I go back from the 4 by 2, I land on the 2.
• 9 - 6 = 3, because if I go back from 9 at 6 I land on 3.

The next section deals with negative problems in the number range up to 20.

Example 4:

• 17 - 3 = 14, because if I go back from 17 at 3 I end up on 14.
• 14 - 2 = 12, because if I go back from 14 by 2 I land on 12.
• 19 - 4 = 15, because if I go back from 19 at 4 I end up on 15.
• 12 - 4 = 8, because if I go back from 12 by 4 I land on 8.
• 15 - 5 = 10, because if I go back from 15 by 5 I end up on 10.
• 18 - 7 = 11, because if I go back from 18 at 7 I end up on 11.
Note:
You can also look at minus tasks from a different perspective and turn them into a plus task. Since 7 - 1 = 6 results in 6 + 1 = 7, or 9 - 6 = 3 and 3 + 6 = 9.
