# What are core and non-core tasks

We'll deal with the core multiplication tables in this article. The following content is offered:

• A Explanationwhat is meant by core tasks.
• Numerous Examples for core tasks are calculated.
• tasks / Exercises so that you can train yourself.
• A Video, which deals with the multiplication of tasks.

Core tasks for 1x1 (multiplication tables) are often dealt with in elementary school and are intended to help students learn to multiply. This is exactly what we want to do here. If you are looking for similar articles, you will find them under Multiply / Take times and Times tables. And that brings us to the core tasks.

What are the core tasks? Well, by this you understand tasks from the multiplication table, in which times 1, times 2, times 5 and times 10 are calculated. The core tasks are:

• 1 · 1
• 1 · 2
• 1 · 3
• ...
• 1 · 9
• 1 · 10
• 2 · 1
• 2 · 2
• 2 · 3
• ...
• 2 · 9
• 2 · 10
• 5 · 1
• 5 · 2
• 5 · 3
• ...
• 5 · 9
• 5 · 10
• 10 · 1
• 10 · 2
• 10 · 3
• ...
• 10 · 9
• 10 · 10

• These are tasks from the multiplication table (1x1).
• They serve to understand the basics of mathematics.
• Core tasks help to learn the multiplication tables by heart. Every student should be able to do the 1x1.

Now let's look at examples of the core tasks. Or to be more precise: We look at the solution to all core tasks.

Note:

If you don't know how to solve multiplication problems (by addition), please have a look at the article Learning multiplication tables online.

As I said, students should actually memorize the following tasks.

• 1 · 1 = 1
• 1 · 2 = 2
• 1 · 3 = 3
• 1 · 4 = 4
• 1 · 5 = 5
• 1 · 6 = 6
• 1 · 7 = 7
• 1 · 8 = 8
• 1 · 9 = 9
• 1 · 10 = 10
• 2 · 1 = 2
• 2 · 2 = 4
• 2 · 3 = 6
• 2 · 4 = 8
• 2 · 5 = 10
• 2 · 6 = 12
• 2 · 7 = 14
• 2 · 8 = 16
• 2 · 9 = 18
• 2 · 10 = 20
• 5 · 1 = 5
• 5 · 2 = 10
• 5 · 3 = 15
• 5 · 4 = 20
• 5 · 5 = 25
• 5 · 6 = 30
• 5 · 7 = 35
• 5 · 8 = 40
• 5 · 9 = 45
• 5 · 10 = 50
• 10 · 1 = 10
• 10 · 2 = 20
• 10 · 3 = 30
• 10 · 4 = 40
• 10 · 5 = 50
• 10 · 6 = 60
• 10 · 7 = 70
• 10 · 8 = 80
• 10 · 9 = 90
• 10 · 10 = 100

### Video multiplication

Core tasks are part of the multiplication table (1x1). And that's exactly what we'll see in the next video. It explains what is meant by a multiplication and how it can be reduced to an addition. Numerous tasks are also calculated with numbers. Try to understand the pre-calculated exercises exactly.
