And As a Heads-Up for a Future HW Assignment, Here Is Something New Due on the Day Of

Mth 211 Jan. 30 th

 Good morning! For the new HW due today (that would be “BLOCK C” from earlier sheet), look for answers to be posted to our Class Wiki within a few days. Meanwhile, your Quizzes & old HW will be coming back to you no later than the end of class on Wednesday.

 This week we’ll continue to talk about some algorithms and estimations for Whole-Number Operations from BLL Section 3.4 & 3.5, and then turn our attention to some work with Integers from BLL Chapter 5 (Sections 5.1- 5.5). So, you can read ahead accordingly.

 And as a heads-up for a future HW assignment, here is something new due on the day of our first Exam:

BLOCK D...Due on February 09th : BLL Assessment 4-3A # 4, 8b, 9b, 11, 12 BLL Assessment 2-1A # 2a, 3, 11b, 15c, 18, 22a BLL Assessment 3-2A # 7a, 8a, 12a BLL Assessment 3-4A # 2a, 4, 6ab, 8, 12, 16, 15, 17 BLL Assessment 3-5A # 3a, 4ab, 11a, 12ac

 Note that most (if not all) of those BLOCK D problems have answers in the back of the text, so you are able to check way ahead of time for correctness. There are also useful problems that you can find, for example in the text’s “Chapter Reviews” (again with lots of answers in the back). Also, although the following useful problems haven’t yet been formally assigned, I share them as an example of the sorts of things we should expect to be able to do:

EXAMPLES OF RECOMMENDED ADDITIONAL PRACTICE

[DC19] Draw the pieces and show the trading that needs to occur in solving this problem:

On Planet Fivey, a farmer has 314five tomatoes. The farmer sells 21five tomatoes, and has how many left?

I need your answer in a base-five numeral, and you do need to draw this out and show what is happening with the pieces as we have done in class.

*** See Other Side *** [DC20] 9342 is usually thought of as 9 Thousands, 3 Hundreds, 4 Tens, and 2 Ones.

But in subtracting 6457 from 9342 using the customary algorithm, we regroup and think of 9342 as

______Thousands , ______Hundreds , ______Tens, & ______Ones

[DC21] Show the use of Partial Products (as in class) in solving 32 x 26

[DC22] Write using exponents w/ lowest bases: 94  23  62

[DC23] Write using a single exponent:

a) 37  95  272

b) 35  21  492  7

[DC24] Show the use of Compatible Numbers in solving

a) 45 + 58

b) 14 x 25 x 20

[DC25] Show your work in giving Range Estimates (as in class) for the following

a) 367 + 689

b) 27 x 36
