Question

СРОЧНОООООО В ряд записаны восемь двоек. Вставляя между некоторыми из них знаки арифметических действий и скобки, можно получать различные числа. Например, числа 446 можно получить так: (222-2+2:2+2)*2=446 Покажите как получить число 2002 ПОЖАЛУЙСТА СРОЧНО За ранее спасибо

Answer 1

2222-222+2=2002 вот и все

Answer 2

Problem Analysis

The problem states that there are eight twos written in a row, and by inserting arithmetic operations and parentheses between some of them, we can obtain different numbers. The goal is to show how to obtain the number 2002 using these eight twos.

Solution

To obtain the number 2002 using the eight twos, we can use the following expression:

((2 + 2) * 2 * 2 * 2) * (2 + 2) = 2002

Let's break down the steps:

1. Start with the eight twos: 2 2 2 2 2 2 2 2. 2. Group the first two twos together and add them: (2 + 2) 2 2 2 2 2 2. 3. Multiply the result by the remaining twos: ((2 + 2) * 2) 2 2 2 2 2. 4. Repeat step 2 and 3 until all twos are used: (((2 + 2) * 2) * 2) * 2 2 2. 5. Finally, add the last two twos together: (((2 + 2) * 2) * 2) * (2 + 2) = 2002.

Therefore, the expression ((2 + 2) * 2 * 2 * 2) * (2 + 2) equals 2002.

Conclusion

By following the steps outlined above, we can obtain the number 2002 using the eight twos provided.
