I´m sorry for the delay. Yesterday we did a lot of things. First we corrected the two exercises of homework about scientific notation and aproximation. After that Mario explained us the irrational numbers (I) and the real ones (R).
Then we did two exercises and finally we did our weekly test. Some exercises were a little difficult and Mario didn´t give us many time.
The homework are the exercises 72, 74 and 82.
REMEMBER THE EXAM OF NEXT WEDNESDAY!
