So, 7+(-4)
=(7-4) (--+)
=3 (put the sign of the bigger no.)

To solve the expression +7 - -4, we first need to understand how to handle the subtraction of integers, particularly when dealing with negative numbers.
Understanding the Expression
- The expression has two parts: +7 and - -4.
- The +7 is a positive integer.
- The - -4 can be confusing at first, but it simplifies to +4 because subtracting a negative number is equivalent to adding its positive counterpart.
