Order Of Operations

B-brackets ( )
E-exponents
D-division (from the left)
M-multiplication (from the right)
A-addition (from the left)
S-subtraction (from the right)

example:

2x2+5=
4+5=
=9

This is a picture on how I did it.

















This is a video to show BEDMAS


ORDER OF OPERATIONS:

1. Annie has been asked to calculate 1.7+6÷2. She claims the answer is 3.85. Do you agree? Explain why or why not.
ANSWER:I don't agree because she didn't follow the order of BEDMAS,the answer should be 4.7



2. Put the bracket in the following expression to get the largest value possible.
What problem solving strategy did you use?3x2.8+6.48
÷4
ANSWER:I would put the brackets here (3x2.8)+6.48÷4.Because multiplucation is a higher value then addition and divion.



3. Create a problem that can be solved using the following expression: 2.5+1.25+5 x 1.6
Lucy went to the mall to see if she can buy a present for her brother.At the mall a little toy car was $1.25,gift raping was $2.50,a bag was $5.00 and a card was 1.50.Lucy only had $10.00 in her poket.Does she have enough money to buy thoughs items.
ANSWER:she wouldn't have enough money because she only has $10.00 and all of the items cost $10.25.

awesome job paolo you did a good job but when i was reading your scribe post the question doesn't really make sense because you didn't use the following expression on the problem, and there is no 1.6 in your problem. Good job. you just need to check on your sentence structure

Nice job!! Just make sure you make it look more organized and neat ( like make the font all the same) so people can understand it more.
