# MAT 221 Week 1 DQ 1

Ashford 2: - Week 1 - Discussion 1

Your initial discussion thread is due on Day 3 (Thursday) and you have until Day 7 (Monday) to respond to your classmates. Your grade will reflect both the quality of your initial post and the depth of your responses.

Evaluating   Algebraic Expressions

Read the following instructions in order to complete this discussion, and review the exampleof how to complete the math required for this assignment:

1. Write your birth date or the birth date of someone in      your family as mm/dd/yy. (Example: March 13, 1981 is written 3/13/81, and      November 7, 1967 is written 11/7/67).
• Now let a = the one- or two-digit month number,
• b = the negativeof the one- or two-digit day       number, and
• c = the two-digit year number.
(Our example:  a = 3, b = -13, and c = 81 or a = 11, b       = -7, and c = 67)

2. Use the following algebraic expressions for parts 3-5      of the discussion:
• A3 – b3
• (a-b)(a2 +a b + b2)
• (b-c)/(2b-a)

3. Evaluate the three given expressions using the a, b,      and c from your birth date.   Make sure that b is negative when      you plug in the values.

4. After you have your math worked out on scratch paper,      go back and verbally describe the steps you took to evaluate the      expressions. Make sure to use each of the vocabulary words at least once      in your writing.
• Did you notice anything interesting about the results       of A3 – b3 and (a-b)(a2 +a b + b2)?       Was this coincidence or do you think there is a reason for this?

5. Incorporate the following five math vocabulary words      into your discussion. Use boldfont to emphasize the words in your      writing ( Do not write definitions for the words; use them appropriately      in sentences describing your math work.):
• Exponent
• Integer
• Variable
• Lowest terms
• Divisor

Your initial post should be 150-250 words in length. Respond to at least two of your classmates’ posts by Day 7. Do you agree with how your classmates used the vocabulary? Did the student handle the negatives in the formulas accurately?

The Ashford Writing Center (AWC) has two kinds of tutoring available to you. Keep in mind that we are writing specialists; please contact your instructor for questions about solving math problems.

• Live Chat– If you have writing-related questions about a topic      before you draft a discussion post or submit a written assignment, you      will now be able to chat live with a tutor for a short (up to 20 minute)      conversation. Live Chat will be available Monday through Friday from      10:00-11:00 am and 4:00-5:00 pm (PST). AWC Live Chat
• Email Paper Review– If you have a draft, partial draft, or even if      you’re having trouble getting started, you can complete a submission form      and email your paper to the AWC for review.
• Writing Tutors will do their best to return your paper       with their comments within 48 hours, not including Saturdays and Sundays.       Please plan accordingly if you would like to receive feedback before an       assignment due date. AWC Email Paper Review

Carefully review the Grading Rubricfor the criteria that will be used to evaluate your discussion.
