При помощи пяти двоек знаков действий и если нужно скобок получи выражения равные числам 1.111,7,4.

Answer 1

Непонятно написанной, если первое число 1, а второе число 111 то так:
2÷2=1
222÷2=111
А если первое число 1111 то так:
2222÷2=1111
А остальное:
(2×2×2×2-2)÷2=7
2+2=4 или 2×2=4

Answer 2

Responding to the question

The question asks to express the numbers 1.111, 7, and 4 using combinations of arithmetic operations and parentheses. Here are the expressions:

1.111 = (1 + 0.1) / 1 7 = 7 4 = 4

Explaining the expressions

For 1.111, I divided the sum of 1 and 0.1 by 1 to get the decimal number. For 7 and 4, I simply wrote the numbers as they are integers.

Using combinations of basic arithmetic operations like addition, subtraction, multiplication, and division along with parentheses allows us to construct equivalent numerical expressions for given values. In this case, I focused on keeping the expressions as simple and clear as possible.
