In 3-10, state the meaning of each expression in part a and in part b, and simplify the expression in each part.The first two problems:
3. a. 20 + (6+1) b. 20 + 6 + 1
4. a. 18 - (4 + 3) b. 18 - 4 + 3What does "state the meaning" mean? I suspect it means to write the equation in words, as explained in this Yahoo Answers response offered by a teacher.
Also, I noticed that every homework exercise in the textbook has a "Writing About Mathematics" section. I wonder if the teacher will correct all the writing assignments.
Lots of writing ahead.
