Order of operation-The language of math

BEDMAS

B-Brackets
E-Exponents
D-Division
M-Multiply
A-Addition
S-Subtraction

Division,Multiply,Addition, and Subtraction is order from Left to right

( For Example )

2+3 *4
2+12=
5=

( PROBLEM )


1.) Annie had been ask to calculate 1.7+6/2.She claims the answer is 3.85.Do you agree?Explain why or why not?

I do not agree because she use addition first before Multiply.If we use the order of operation Multiplication must be first to Addition.


2.) Put Brackets in the following expression to get the Largest value possible.What problem solving strategy did you see?
3*2.8+6.4/4

3*2.8+6.4/4=
3*(2.8+6.4/4)=
3*(2.8+1.6)=
3*4.4=
13.2

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


2.5+1.25+5*1.6=
(2.5+1.25)+(5 * 1.6)=
3.75+(5 * 1.6)=
3.75+8=
11.75=

Good Job MJ! You just forgot to put a link, video and an image. You also might also want to put an image after the first question. It will be easier to understand.
