Question

Вычисли значения разностей, используя способ поразрядного вычитания.39-7 82-2

Answer 1

39-это 3 дес. 9 ед.  нужно из 9 ед вычесть 7 ед. или записать вот так
30+(9-7)=30+2=32.
82-это 8 дес.2 ед. от 2ед.вычитаем 2 ед.=0 или записываем вот так
80+(2-2=0) , 80+0=80

Answer 2

Calculation using Bitwise Subtraction

To calculate the differences using bitwise subtraction, we can perform the following steps:

1. Convert the numbers to binary representation. 2. Perform bitwise subtraction on each bit. 3. Convert the result back to decimal representation.

Let's calculate the differences for the given numbers: 39-7 and 82-2.

# Calculation for 39-7:

1. Convert 39 and 7 to binary: - 39 = 100111 - 7 = 111

2. Perform bitwise subtraction on each bit: - Subtract the rightmost bits: 1 - 1 = 0 - Subtract the next bits: 1 - 1 = 0 - Subtract the next bits: 1 - 1 = 0 - Subtract the next bits: 1 - 0 = 1 - Subtract the next bits: 0 - 0 = 0 - Subtract the next bits: 0 - 0 = 0

3. Convert the result back to decimal: - The binary result is 000000, which is equal to 0 in decimal.

Therefore, the difference between 39 and 7 is 0.

# Calculation for 82-2:

1. Convert 82 and 2 to binary: - 82 = 1010010 - 2 = 10

2. Perform bitwise subtraction on each bit: - Subtract the rightmost bits: 0 - 0 = 0 - Subtract the next bits: 1 - 1 = 0 - Subtract the next bits: 0 - 0 = 0 - Subtract the next bits: 1 - 1 = 0 - Subtract the next bits: 0 - 0 = 0 - Subtract the next bits: 1 - 1 = 0 - Subtract the next bits: 0 - 1 = -1 (carry over)

3. Convert the result back to decimal: - The binary result is 1111110, which is equal to -2 in decimal.

Therefore, the difference between 82 and 2 is -2.
