You can put this solution on YOUR website! The first is -17/12. One puts each over a common denominator and subtracts. Both are negative; the answer is more negative
second is +1/12, because the second term is added (two negatives)
third is +1/4, multiplying numerators and denominators, and two negative signs is +
fourth is +(2/3)(4/3=+(8/9); invert and multiply, and two negative signs is +
