### 5/5 — Basic but essential

*2025-10-29, version 2.3*

Still a top notch mental maths Quiz that everyone should have. Mandatory.

### 5/5 — Kopfrechnen

*2025-09-18, version 2.3*

Super Tool zum üben, für jung und alt! Top!

### 1/5 — Negative number selection

*2025-04-26*

In the multiplication quizzes I can’t see where the negative number selection is located.  Poor design and poor rules explanations.

### 5/5 — Great morning workout

*2024-01-22, version 2.3*

I go through several exercises every morning for a great workout, that gets all the necessary cogs turning and ‘the little grey cells’ washed and ready for action.  

You’d be surprised how much you’ve forgotten, and how easy it is to miscalculate and execute correctly even simple terms.

If you forgot math, so you can do it for fun and enjoy it to memorize it again! :)
