Question

1) 101111+1011112) 101111-1001113) 10011-10010С объяснением пожалуйста

Answer 1

101111+101111 = 202222 .



начинаю объяснять слева на право следите.


101111+
101111

1+1=2 это сотни тысяч ( первая цифра в ответе)
0+0=0 десятки тысяч (2 цифра в ответе) их нет и там 0
1+1=2 (3 цифра) это единицы тысяч.
1+1= 2 (4 цифра) это сотни
1+1=2 (5 цифра) это десятки
1+1=2 (6 цифра) это единицы.
ответ: 202.222
101111-101111=0 это ясно .
10011-10010=1
1+10010=10011 это тоже ясно.

Answer 2

1. To add the binary numbers 101111 and 101111, we can use the following process:

   1 0 1 1 1 1 (101111)

• 1 0 1 1 1 1 (101111)

---

1 0 1 1 1 1 0 (2110)

The first step is to add the rightmost bits, which are both 1. This gives us a sum of 0 with a carry of 1. We then move on to the next bit, which are both 1 again, and add the carry from the previous step. This gives us a sum of 1 with a carry of 1. We continue this process until we have added all the bits, and the final result is 1011110 in binary or 46 in decimal.

2. To subtract the binary number 100111 from 101111, we can use the following process:

   1 0 1 1 1 1 (101111)

• 1 0 0 1 1 1 (100111)

---

0 0 1 0 0 0 (1000)

The first step is to subtract the rightmost bits, which gives us a difference of 0. We then move on to the next bit, and since 1 is greater than 0, we can subtract as usual and get a difference of 1. We continue this process until we have subtracted all the bits, and the final result is 1000 in binary or 8 in decimal.

3. To subtract the binary number 10010 from 10011, we can use the following process:

   1 0 0 1 1 (10011)

• 1 0 0 1 0 (10010)

---

0 0 0 0 1 (1)

The first step is to subtract the rightmost bits, which gives us a difference of 1. Since we can't subtract 0 from 1, we borrow a 1 from the next bit over and subtract 1 from 2, which gives us 1. We continue this process until we have subtracted all the bits, and the final result is 1 in binary or 1 in decimal.
