B.E.D.M.A.S means....

B - racets ( )
E - xponents 2*
D - ivision
M - ultiplication
A - ddition
S - ubtraction

Division and multiplication, addition and subtarction are in order left to right.

Example:

1+2x3/2=

1+6/2=

1+3=

4=

Remember to follow the BEDMAS. "Step by step"


Problem and solution:

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?

Annie is wrong because she added the numbers first then she divide it. She didn't follow the BEDMAS. The right answer is 4.7, here's how I got it.

1.7+6/2=
1.7+3=
4.7=

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

I used multiplication and division.

Multiplication:

(3x2.8)+6.4/4=
8.4+6.4/4=
8.4+1.6=
10=

Division:

3x2.8+(6.4/4)=
3x2.8+1.6=
8.4+1.6=
10=


3.)Create a problem that could be solve using the following expression. 2.5+1.25+5x1.6

Clarice has $15.00. She went to SevenEleven and bought 5 medium Slurpee for her friends. Each Slurpee cost $1.60. She bought 2 large bag of chips which is cost 2.50. She wanted to buy donut, the donut cost 1.25. Does she have enough money to buy them all?

Yes, Clarice has enough to buy them all. Here's how I solve it.

2.5+1.25+5x1.6=
2.5+1.25+8=
3.75+8=
11.75=
