-3-7/9+5/6 = -83/18 or -53/18... thanks for you help me!
Have you learned how to add and subtract fractions?
In mathematics, you don't understand things. You just get used to them.
I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
