7 + (-5) + (-3) = -1
explain
When you have a positive number and add a negative number to it, you can think of it as subtracting the absolute value of the negative number from the positive number.

So, in this case, 7 + (-5) is like subtracting 5 from 7, which gives us 2.

Then, when you add another negative number, such as (-3), it is like subtracting the absolute value of that negative number from the result of the previous addition.

Therefore, 2 + (-3) is like subtracting 3 from 2, which gives us a final result of -1.
