Order of Operations

Order of Operations:

B-Brackets
E-Exponent
D-Division
M-Multiplication
A-Addition
S-Subtraction
Here is an example we did in class:












1.)Annie has been asked to calculate 1.7+6 divide by 2.


She claims the answer is 3.85.


Do you agree?Explain why or not.

Answer:
I do not agree because she didn't do the B.E.D.M.A.S.The correct answer would be 4.7.
This is how i did do get 4.7 :








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

There could be two possible answers:







Create a problem that can be solved using the following expression:

Meagan had money and her parents borrowed it. her mom ows her $2.5 and her dad ows her $1.25 and each of her sibling ows her money Cj, John, Joshua, Kisha, and Marry ows her $1.6. She collected all of them and got $11.75
