Order of operations
B- Brackets
E- Exponents
D- Division \ Division and Multiplication
M- Multiplication / Like Mother and father. (EQUAL)
A- Addition \ Addition and Subtraction
S- Subtraction / Like brother and Sister. (EQUAL)
| Rule 1: | First perform any calculations inside parentheses and check if there are any exponents. |
| Rule 2: | Next perform all multiplications and divisions, working from left to right. |
| Rule 3: | Lastly, perform all additions and subtractions, working from left to right. |
2 + 3 x 4 =
\ /
2 + 12 = 14
Question 1:
Annie had been asked to calculate 1.7+6÷2. She claims the answer is 3.85. Do you agree? Explain why or why not.
Solution: Nope because
1.7+6÷2
1.7+ 3 (6 divided by 2 is 3)
1.7+3=4.7
Question 2:
Put brackets in the following expression to get the largest value possible. What problem strategy did you use?
3x2.8+6.4÷4
Question 3:
Create a problem that could be solved using the following expression.

Good job Kamille, you put everything we needed to know about order of operations!! :)
Good job i really like the post and you have everything we need
I really like your scribe-post.On the bedmas, the M has to be multiplication. I understand the video, it really helped me with the order of operations.
goodjob kamille. this really helped me what I missed during math when I was away (: you had everything that I could catch up on
great job explaining everything in class i liked the video it helped me a lot maybe you can add a different picture but great job.
Good job kamille. You forgot to put question three but either than that, your scribe was great. Also you could have put that multiplication and division are like mom and dad and addition and subtraction are like brother and sister.
Hi Kamille, I really liked your Scribe post. You put everything that we did in class.I suggest to you that you should make the fot size bigger so it's easier to read. You did a great job Kamille. :D
Hi Kamille, I really like your scribe, but next time make the font a little bigger because it's really hard to see.
Hi Kamille. Good scribe post! On your rules for order of operations, don't forget to check for exponents. Also make sure your font color is dark enough to see, and your font size should be bigger. Your video helped. Good Job!
Hi Kamille, Great work on your scribe post! I really like the picture you add. Kamille, you forgot to put the solutions for numbers 2 and 3 for the homework questions. But you did put the solution for number 1, and I agree with you on that. Always remember to solve the multiplication or division questions before addition or subtraction! Great work Kamille!
Kamille, Great job on your scribe post! I really liked how you gave us a choice on the links. But next time could you make the font a little bigger. And you forgot to answer questions 2 and 3 but other than that you did a great job!
