This is a straightforward problem. Remember that when adding a negative number, you are actually subtracting:

Be sure to remember that the first number is also negative, meaning we are subtracting a number from a negative number:

The answer is -6.25.

When two negative numbers are being divided, our answer is positive. The quotient is .

When multiplying with a positive number and a negative numberr, our answer is negative. The product is .

results in when simplifying with the foil method as follows:
