Order of operations (language of Math)


B-Brackets ( )E-Exponents a2
D- Division
M-Multiplication ( order from left to right)
A- Addition ( order from left to right)
S- Subtraction

Here is a Example :





1 Annie has been asked to calculate 1.7 + 6 ÷ 2=
she claims that the answer is 3.85 do you agree? Explain why or why not.

A: i don't agree because she didn't use the bedmas which is the order of operations and the answer would be 4.7

2 Put brackets in the following expression to get the largest value possible. what problem solving strategy did you use? 3x2.8 + 6.4÷4

A: (3x2.8)+ 6.4÷4 = i rounded 2.8 into 3 so it would be 3x3

3 Create a problem that could be solve using the following expressions
2.5 +1.25 + 5 x 1.6

Expression: Ken has $10.50. He wen't to a store to buy a drink which cost $1.25. He also bought 5 bags of candy which is $1.60 and bought 1 milk for his brother which cost $2.50. Does he have enough money to buy all those items?

A: No because All those items was $11.75 and he only has $10.50

Here is a video of a Bedmas:
