Symbols and Expressions (CA SS: 1.0)

We went over the properties in class and discussed some mnemonics. We began covering the vocabulary for lessons 1 and 2 in chapter 1.

Chris, if you're talking about the vocab Mr. Gerson was telling us about, then no- we are continuing in class tomorrow.

On Studyisland, a couple of questions said "closure". What property was that talking about?

I don't know what closure means either. Are we going to learn that further on as we go through the chapters?

Mr. Gerson said...

I love it. You guys answered almost all of the questions for each other. Good job.

There are 3 properties of equality at the end of Chapter 2 that I have not covered yet. As far as the closure property, StudyIsland will give you an explanation if you click on the right link, or print out the problem and bring it to class for me to explain.

Mr. Gerson said...

Closure basically means that since a is a real number and b is a real number then a + b is a real number. Since that won't make much sense, print a problem and bring it in for me to explain.

ZornRockman said...

thank you mr gerson that was good to know

ZornRockman said...

alos for fifth perod i'm bringing a copy of the closure question

Anonymous said...

Thax Guys! I cant print out the Question because we're out of paper, but I'll copy and paste:
Mr. Thornton was describing the mathematical property of "closure" to his class and said that while integers may be closed under addition, subtraction, and multiplication, the integers are not closed under division. Which of the following examples proves his point?
A:32 ÷ 8
B:45 ÷ 5
C:6 ÷ 6
D:24 ÷ 9

Mr. Gerson said...

The question says closed as "integers"

A:32 ÷ 8 =4 integer
B:45 ÷ 5 =9 integer
C:6 ÷ 6 =1 integer
D:24 ÷ 9 =8/3 not an integer

Understand?

ZornRockman said...

oh i get it because of the 8 and the 3

Mr. Gerson said...

24/9 is 8/3.

8/3 is a repeating decimal: 2.66666...

8/3 is real and rational but not an integer.

Thank you everyone, especially Mr. Gerson for helping me understand what closure means. Now it makes sense and can help me out with StudyIsland.
Thank you SO much!!
