This is a video explaining BEDMAS.
1. 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.
She is wrong because she didn't follow the Order of Operations and the correct answer is 4.7. I got my answer by doing this:
1.7+6÷2=
1.7+3=
4.7
1.7+3=
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=
There are 3 possible answers. (3 x 2.8) + 6.4 ÷ 4 = 10, 3 x 2.8 + (6.4 ÷ 4) = 10. and (3 x 2.8) + (6.4 ÷ 4) = 10.
3. Create a problem that could be solved using the following expression. 2.5 + 1.25 + 5 x 1.6.
Eric wants to buy a keyboard the cost 11.75 but he only has 1.60 dollars
he went home and ask his mom for 5 dollors
but he still missing 3.75
so he went to his uncles house to ask for money and his uncle gave him 2.50
he still missing 1.25 so he went to his sister for 1.25
This is an example we did at class:
Here is an Order of Operations game .Thank you for reading. [:
