Answer 2

Let's solve each of these mathematical expressions step by step:

1. $3 - 5 - (+7)$

To subtract a positive number, you can simply subtract it:

$3 - 5 - 7 = -9$

2. $3.6 - (-5)$

Subtracting a negative number is the same as adding its positive counterpart:

$3.6 + 5 = 8.6$

3. $4.6 - (+2.5)$

To subtract a positive number, you can simply subtract it:

$4.6 - 2.5 = 2.1$

So, the results of the given expressions are:

1. $3 - 5 - (+7) = -9$

2. $3.6 - (-5) = 8.6$

3. $4.6 - (+2.5) = 2.1$
