Order of Operations

B ~ Brackets

E ~ Exponents

D ~ Division

M ~ Multiplication

A ~ Addition

S ~ Subtraction

E.g.
2 x 4 + 1 =
\ /
8 + 1 =
9


Here is a video to help you:


Homework :
1.
Annie has asked to calculate 1.7 + 6 ÷ 2. She claims the answer is 3.85. Do you agree? Explain why or why not.

No, because:
1.7 + 6 ÷ 2 =
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.
( 4
÷ 2 ) + ( 6.7 x 2 ) = 15.4




Here is a quick game.

Hey Danilyn! Good job for making a scribe post. You had everything we needed. Try putting an image. This helps: http://s3.amazonaws.com/TextBookImages/na-0009.03.png
You could also put the steps for bedmas. Anyways, thanks you. ~:D~

Hi Danilyn, great scribe post! But on question #3 the question is suppose to be 2.5 + 1.25 + 1.6. Not (4 divided by 2) + (6.7 x 2)
And also the question said to create a problem that could be solved using the following expression. So I think you need to create a problem to go along with it. Other than that, awesome scribe post!
