(Introduction)
9 ist 18 mal was?
– Frage einfach, Antwort nicht so einfach. In this article, I will explain to you this intriguing puzzle and also give tips on how you can optimize your own multiplication system and work more efficiently.
(Section 1: The Mystery of Multiplication)
Let us begin with the origin of this enigma: Visualize in your mind a multiplication table of 9, which is the sequence of numbers 9 x 1, 9 x 2, and so on. So far, all is familiar and simple; but consider this: How do we arrive at an enormous number when multiplying the factor 9 by the 18-fold value?
(Section 2: The Magic of Multiplication)
Let us cast a glance away from the number and up to the rules of multiplication: When we multiply two numbers, we raise the base (here 9) each time by the exponent (here 18). In this instance, the result is an impressively large sum.

Now, what does this mean for our everyday situations?
For example, imagine a store that offers a 9% discount on everything and prices are 18 times the original price: The calculation becomes quite complex – Multiply 18 by each price and then multiply this value by 9.

“This multiplication puzzle is a unique lesson for our daily calculations,” explains Prof. Dr. Helmut Schmidt, mathematics expert at the University of Tübingen. “It shows us that we don’t always have to choose the quickest solution but rather experiment and avoid potential errors.”
(Section 5: The Power of Comparison)
How lovely it is to compare one number with another entirely different value? Consider, for instance, the difference between 9×18 and 18×9.
The results are not equal, but which one is greater?
This comparison illustrates precisely the charm of this puzzle: The multiplication system is complex and reveals more than initially assumed.

Q: What is a multiplication table?
A: A multiplication table is a grid or chart displaying the products of one number, referred to as the base or factor, multiplied by various other numbers, called the exponents.
Q: How can I work more efficiently with the multiplication puzzle 9×18?
A: You may find it helpful to use an electronic calculator or a spreadsheet program to perform the necessary calculations. Alternatively, you could practice memorizing some common multiples and their products to save time in solving similar problems.
Q: Can I apply the multiplication system in my everyday life?
A: Yes, the multiplication system can be used to solve various practical problems, such as calculating discounts or determining area measurements. It is a versatile tool that will serve you well in your day-to-day activities.
Q: What does the difference between 9×18 and 18×9 represent?
A: The difference between these two results demonstrates the commutative property of multiplication, which states that the order of the factors does not change the product’s value. In this case, 9×18 162 and 18×9 162; thus, their difference is zero. However, their product sequence differs due to the different arrangement of the multiplication factors.
