Mental arithmetic tasks with solutions: https://www.gut-erklaert.de/mathemati... Mental arithmetic explanation: https://www.gut-erklaert.de/mathemati... Test general knowledge: https://www.gut-erklaert.de/allgemein... You will learn mental arithmetic in this video. I will show you how to calculate in your head using the 4 basic arithmetic operations of addition, subtraction, multiplication and division. I will also show you a simple trick for how to do this with percentages. For the basic arithmetic operations and percentage calculations, you will be shown various examples and shown why these variants are best suited for mental arithmetic. Important: Of course, you must be aware that you have to be able to remember one or two numbers in your head. But you can't do without them completely. Mental arithmetic is expected by schools as early as elementary school. Pupils should be able to calculate at least smaller tasks involving plus, minus, times and division in their head and not using a calculator. After the video, you should do our tasks on the topic yourself. ▬▬▬▬▬▬▬▬ Mathematics well explained. This is exactly what the gut-erklaert.de YouTube channel offers you. We start with the 1st grade of elementary school and build up step by step until the Abitur. We take a closer look at very well-known topics such as the Pythagorean theorem, the PQ formula, equations and binomial formulas. But less well-known topics such as biquadratic equations are also covered. For each topic you will be shown why you need it and examples are calculated and explained. In the next few years we will expand to include other subjects. We will also devote ourselves to physics, biology and chemistry as well as the languages ​​German, English and French. Content on history, geography and computer science is also planned. ▬▬▬▬▬▬▬▬ ► ???? Website: https://www.gut-erklaert.de/
