Order of Operations

B-Bracets ( )
E-Exponents a2
D-Division------->in order from left to right
M-Multiplcation--^
A-Addition------->in order from left to right
S-Subtraction------^

Here is one of the examples we did in class


These are some questions on, Order of Operations.


1. Anne has been asked to calculate 1.7 + 6 / 2. She claims her answer is 3.85. Do you you agree? Explain why or why not.

A. I do not agree with Anne, because she didn't use BEDMAS. If she did use it her answer would be 4.7.

2. Put bracets in the following expression to get the largest possible value. What problem solving strategy did you use? 3 x 2.8 + 6.4 / 4

A. I would put the bracets here, (3 x 2.8) +6.4 / 4. The strategy I used was that I saw there was multiplcation and I know if you multiply you can get a higher answer. Then I multiplied 3 x 2.8 and I got, 8.4.

3. Create a problem that could be solved using the following expression. 2.5 + 1.25 + 5 x 1.6.

A. John wants to buy a tool for work that is $11.75. But John notices he only has $2.50 in his wallet. Then John goes home and finds $1.25 in his piggy-bank. But he is still $8.00 short! So he decides to have a quick garage sale with 5 things in it that costs $1.60 each. At the end of the day all 5 items were sold and he got his $8.00. Then he goes to the store and buys that tool.
