Answer 1

Ответ:

1•5=1+1+1+1+1+1 1•0=5

Answer 2

It looks like you're trying to demonstrate a mathematical concept where multiplying a number by 1 results in the same number, and you want to extend this concept to show that multiplying any number by 1 also equals that number.

In your examples:

1×5 = 1+1+1+1+1, which simplifies to 5. 1×a = a, where "a" represents any real number.

So, yes, when you multiply any number by 1, the result is that same number. This is a fundamental property of multiplication known as the multiplicative identity, where 1 is the identity element for multiplication.
