Question

12+13= 30 доказательство

Answer 1

12+13=30 ложь
12=(10+2)
13=(10+3)
(10+2)+(10+3)=(10+10)+(2+3)=20+5=25
12+13=25 истина

Answer 2

The statement "12+13=30" is actually incorrect. The correct mathematical addition of 12 and 13 is:

12 + 13 = 25

If you add 12 and 13 together, you get 25, not 30. This can be verified by using basic arithmetic:

12 + 13 = 25

There is no valid mathematical proof that would support the claim that 12+13 equals 30, as it goes against the fundamental principles of addition.
