Today we did number of the day and we work on something called order of operation. We a word called BED MAS. B is for brackets, E is for exponents, D is for division, M is for multiplication, A is for addition and S is for subtraction. Addition and Subtractions are brothers.multiplication and division are sisters.1 brackets are (3+1) 2 Exponents are 52 3 divide or multiply in order from left to right 4 addition or subtraction in order from left to right.
(1.75-0.5) times (4.2\0.6+7.3-1.2
0.70 times ( 4.2 \ 0.6) + 7.3 -1.2
0.70 times 7 + 7.3 - 1.2
4.9+7.3-1.2
4.9+6.1 =11
What sign goes were
5.2\4+2.1
1.3+2.1
3.4 =3.4
2 times 3 \ 6 + (2-1)
2 times 3 \ 6 + 1
6 \ 6 + 1
1+1 = 2
Annie has been asked to calculate 1.7 + 6 \2. she claims the answer is 3.85. do you agree or disagree? Explain why or why not. I think it is wrong because I 1.7 + 6 \ 2 then 1.7 + 3=4.7 so I think it is wrong.

ReplyDeleteGood job Kris. You might have put the colour and the format differently though. Make sure your editing is better. On the question I think your calculation is correct and Annie's is incorrect because of the reasons you wrote down. It's easy to understand because I wasn't in that class today. Good job and I agree with you.
ReplyDeleteGood Job Kris!!You explained everything well,but you should change the colors more..But everything else is ok.I think you are correct(Kris) because I did the steps we did earlier and I got the same answer you did.GOOD JOB!!:D:P
ReplyDeleteGood job! I liked how you shared your opinion for the problem you guys worked on in class. In your first paragragh I didn't really understand the part about brackets. You should work on your editing. Other thatn that you did a good job.
ReplyDeleteNice job Kris. I liked how you made your font purple.. it really got my attention. For improvement maybe you could've made the order of operation things a different paragraph and color it a different color. Also, try to check your blog over and over again to make sure the editing is correct. I didn't really get the part where it said what sign goes where, next time can you explain on what to do and how to do it? Also, when you said you did number of the day, you could've put what the number of the day was. Overall... niiice job! (:
ReplyDeleteNice job Kris. :)I also have the same opinion as what Nils said. To make sure your editting was better. For the Annie part, I got the same answer as Suzie. I think next time, you should put BEDMAS together, instead of putting it as BED MAS. Other than that, good job. "Nice" Miley Cyrus video. ;)
ReplyDeleteNice job! You did a great job explaining what you did today. You explained everything pretty well, but you could have said that / means divided by. Also edit your post. You kind of managed to mess up the title (no offense). Oh yeah, you shouldn't put the answer to our homework on the blog where people can cheat and not put any effort into it (again no offense). Don't forget to label your post. And finally... Miley Cyrus?! In math?! Really? Wow. Anyways, good job. :)
ReplyDeleteI think you did an okay job in explaining the order of operations. But your punctuation, grammar, and spelling wasn't very good. You should check over your work. Remember to read it over and to do spell check. Also the answer to (1.75-0.5)x(4.2\0.6)+7.3-1.2= 11 is wrong! The answer is supposed to be 7.58. You messed up on 0.75-0.5=. You put 0.7 as the answer, when it is supposed to be 0.25. For, "What sign goes where?" you forgot to put what signs you are putting where. I agree with you, Kris because Annie started with 1.7+6/2. But you are supposed to start with division first before addition.
ReplyDeleteSo it's supposed to be;
1.7+6/2=
1.7+3=
4.7
Next time make your post more organized, read over your work and play around more with sizes. Make sure your links, pictures, and videos relate to your topic!
Nice job I like how you explained what you did in class today. Like what the other people said you should check your grammer and spelling. And I feel the need to say this: Miley Cyrus?! Out of all the songs ever made why did you have to pick that one! And that was not math related at all! Other than that good job!
ReplyDeleteYou did a great job! :) but I think you should of played around with colors and I got confused with the question about Annie, I think you should spread out your letters so its easier to read.I agree with your answer because you followed the rule
ReplyDelete1.7+6/2=
6/2=3
3+1.7=4.7
(BED MAS)
You did a GREAT JOB on the questions but next time you do a scribe play around with the colors:).
Good job Kris! I got the same answer. 1.7 + 6 = 7.7 and divide it by two, and you will get 3.85. me and my dad keep arguing about this he keeps saying that it was something else. GOOD JOB again! (:
ReplyDeleteGood job. I like how you changed the colour rather than leaving it black. Next time you should save the picture and then put it in the blog instead of putting the link. I agree with you because you did division first and then added. Unlike Annie who added first.
ReplyDeleteGood Job Kris! I liked your blog. But I have a few negative comments. Sorry! You made mistakes in grammar, punctuation, and when you wrote \ at first I didn't know what it meant, you should have said it means divide. Good job. Miley Cyrus video...lol wow. :D :P kk Good job.
ReplyDeletenice job, Kris! i noticed that you made a some little mistakes with grammer, and such, but besides that, i agree with your answer.
ReplyDeletebest of luck!
Good Jobbbbbbbbbbbbbb!!!!!!!!!!!!!!!!!!!!!Kris.
ReplyDeleteI liked it but some of it did'nt make sence.
Next time read it then you'll know if you wrote something that dosn't make sence. Keep it up dude.

ReplyDeleteKrus that was a good post and i liked the miley cyrus video it was anwsome and by the way GOOD JOB best of luck
ReplyDeleteGreat job, Kris! I deleted my old comment because I had made a big spelling mistake. There were some spelling and grammar mistakes, but other that that, it was a good scribe. I agree with you for Annie's problem. I did it the same way you did and got 4.7. Maybe next time you should put a video that is more related to math.
ReplyDeleteGreat Job, Kris! I deleted my other comment, because i re read on what i put and i found out that i did the whole thing wrong, You should put what is about the topic not some random song, and pick a song that everyone likes i hate that song ! Good job, i agree with you for annie's problem i liked how you explained everything.

ReplyDeleteGood Job Kris!! I like the way you used the colour and how you explained everything. Everything could have been perfect if you didnt put the Miley Cyrus video and put a video that had to do with the topic. Other then that everything is perfect.
ReplyDeleteGood Job Kris! I liked the way you put the colour purple it makes attention. You should of put math video not a miley cyrus video shes not math! Well Good job Kris!
ReplyDeleteGood job Kris!!! I loved the way you explained
ReplyDeletebedmas. But you should try to change the colour

Good job Kris you did really good
ReplyDeleteNice scribe post Kris. I followed the link to that picture, good choice of a picture to make you understand BEDMAS. I also watched the Party in the USA video, even though it has nothing to do with math:)Great job!
