Order of Operations


B-brackets
E -exponents
D-division
M-multiplication
A -addition
S-subtracting

Division and multiplication are equal so witch ever one is first, going left to right is the one you do first.

The same with adition and subtracting they are equal so witch ever one is first, going left to right is the one you do first.


Example

(10-5)x5+5 =

\/

5x5+5 =

\/

25+5=

\/

30


Home work

Annie has asked to calculate 1.7 + 6 ÷ 2. She claims the answer is 3.85. Do you agree? Explain why or why not.
1.7 +6÷ 2
1.7+3 since 6÷ 2= 3
1.7+3=4.7


2. Put brackets in the following expression to get the largest value possible. What problem strategy did you use?

3 x 2.8 + (6.4 ÷ 4)=10


3. Create a problem that could be solved using the following expression.

2.5 + 1.25 + (5 x 1.6)=11.75

Hi Jason, nice job on your scribe-post. You explained everything that we did in class. You should check your spelling, you forgot another d in addition, and witch has to be which. I like your example question, it follows the order of operations.

Hi Jason, your scribe post is really good but maybe you could make "BEDMAS" bold so it stands out.

Great work, I agree with you on question #1. Alway remember to do the multiplication or division before addition or subtraction! Great work Jason!
