Answer 1

да тут изи))

Пошаговое объяснение:

2) (+9)-(-5) - тоже самое,что и 9+5=14(минус на минус - плюс)

(+4)-(+4) - тоже самое,что и 4-4=0(минус на плюс - минус)

(-6)-(-11) - тоже самое,что и -6+11=5(минус на минус - плюс)

3) (-7,1)-(-7,1) - тоже самое,что и -7,1+7,1=0(минус на минус - плюс)

(-7,1)-(+7,1) - тоже самое,что и -7,1-7,1=-14,2(минус на плюс - минус)

(+7,1)-(7,1) - тоже самое,что и 7,1-7,1=0

Answer 2

1. To simplify the expression (+9)-(-5), we can rewrite it as (+9)+(+5) because subtracting a negative number is the same as adding its positive counterpart.

Therefore, (+9)+(+5) equals +14.

2. For the expression (+4)-(+4)(-6)-(-11), let's break it down step by step:

First, we have (+4)-(+4), which simplifies to 0 since subtracting a number from itself results in zero.

Next, we have 0(-6)-(-11). Multiplying 0 by any number will always result in zero, so we have 0-(-11).

Subtracting a negative number is the same as adding its positive counterpart, so 0-(-11) becomes 0+11.

Therefore, the final result is 0+11, which equals 11.

3. In the expression (-7,1)-(-7,1)(-7,1)-(+7,1)(+7,1)-(7,1), it seems that the numbers are in a different format. It appears to be using comma as a decimal separator instead of a period.

If we interpret the numbers as (-7.1)-(-7.1)(-7.1)-(+7.1)(+7.1)-(7.1), we can simplify it as follows:

(-7.1)-(-7.1) equals -7.1+7.1, which gives us 0.

Next, we have (0)(-7.1)-(+7.1)(+7.1). Again, multiplying any number by zero will result in zero. So we have 0-(+7.1)(+7.1).

Finally, we have 0-49.41, which simplifies to -49.41.

Therefore, the final result is -49.41.
