Order of Operations

When you are doing order of operations you need to learn the word bedmas
B- Brackets
E- Exponents
D- Division
M-Multiplication
A- Addition
S- Subtraction

 Here is how you do it

1st check if there are brackets
 2nd check if there are Exponents
3rd check if there is multiplication or division
4th check if there is addition or subtraction

eg



 Here is a video that might help you


Here was our Homework


1. Q. 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.
1. A. I do not agree. Because if the question is 1.7+6÷2, you would have to divide first, here how it would look if you did; 1.7 + 6 ÷ 2 =
                   1.7 + 4 =
5.7 =

2. Q. Put brackets in the following expression to get the largest value
possible. What problem solving strategy did you use?
(3 × 2.8) + 6.4 ÷ 4. I used order of operations to solve the problem.
2. A. Red= Answer

3. Q. Create a problem that could be solved using the following
expression.
2.5 + 1.25 + 5 × 1.6
3. A. How much money will I need if I need to buy an Apple pie[$2.5], Bottle of coke[$1.25], and 5 chocolate bars[$1.6 ea.]?
