3 * 2 = 4 how can you get?

Good day to all, the teacher gave the task of logic 3 times 2 equals 4 (3 * 2 = 4) how can I get this?
there is an option like this
(60-60) = (40-40)
6*(10-10) = 4*(10-10)
6=4
3*2=4
but I would like to play it safe and look at other possible options, otherwise I can’t believe that such an easy solution pulls on the machine, if anyone has ideas, then please write)
a question on logic

I'm the only one sure that the question in the original including the correct meaning - ANOTHER?
The TC has the operation of multiplying 2 numbers and it turns out that you need to beat someone with a shovel along the ridge before he shows his disrespect for Pythagoras.
The question pulls on the machine for visiting traumatology. Sector prize on the reel...
prove that (3*2) = 4
=> 6 = 4
Here's a variant without extracting the roots, but with quite intense juggling of mathematical expressions.
Let c = a + b, where a and b are any numbers.
a2 - b2 = (a - b) (a + b)
Since c = a + b, we get the identity: a2 - b2 = (a - b) c
Expand the brackets: a2 - b2 = ac - bc
Add the product ab to both parts : a2 + ab - b2 = ac - bc + ab
Move right b2: a2 + ab = ac - bc + ab + b2
Move left ac: a2 + ab - ac = ab - bc + b2
Small grouping: a (a + b - c) = b (a + b - c)
We reduce the expressions in brackets: a = b
Since a and b are arbitrary numbers, it turns out that any number is equal to any number. Indeed, a trick that is quite common among cheaters and mathematicians is used here - juggling. The answer is adjusted to the condition of the problem.

Hey, you can't divide by zero.

In general, you can redefine the operation of multiplication. Historically, multiplication is taking the first number a second number of times. And we will agree with you and no one will be able to interfere with this, that when multiplying, it will be necessary to take a tax on the operation in the amount of a third of the result, then:
3 * 2 = 4
3 * 3 = 6
6 * 6 = 24

None, it's logical

How is it that 6=4? Get a drug addict.
6*(10-10) = 4*(10-10)
0 = 0,
not 6=4

If we assume that 3, 2 and 4 are variables, then we can do the following:

``````число 3 = 1; // Также можно поставить 0 или любое число.
число 2 = 1; // Также можно поставить любое число или 0.
число 4 = 1; // Можно поставить 0.

Если(3 * 2 == 4)
ВсёСходится();``````

If "programming" confuses, then variables can be understood as the number of some objects.
For example, "three-thirds of an apple is multiplied by two, and four halves of apples are obtained", i.e.
`(3 * (1 / 3)) * 2 == 4 * (1 / 2); // 2 == 2`

Change the number system, in whatever case it will be so ....

Each logical construction is true only within a certain representation. In this case, the problem can be solved as follows - to choose a representation in which the statement "3 times 2 equals 4" is true. Finding such a representation is, of course, easy, for example, by assuming that it is a password.
