What is BEDMAS?

Today at math we were learning BEDMAS.

1st B
- ( brackets )
2nd E- exponents 32, 43
3rd D- division
----M
-multiplication
4th A- addition
----S- subtraction

BEDMAS describes as the order of operations or the order of which you operate an equation.











To practice our knowledge, we were given equations to solve:

A. 2+3x4=
2+12=

14


B. 10-6÷2=
10-3=
7


C.(2+3)x4=

5x4=

20


D.(10=6)÷2=

4÷2=

2


E. 8÷22=

8÷4=

2


F. 4x3÷2+5=

12÷2+5=

6+5=

11


G. Create an equation that includes +, -, x, ÷, exponents, and brackets. The answer will equal 6. You can't repeat any number more than once and you can't use zero. Explain why you think my equation is right or wrong. If wrong, give an equation that is right and tell me what I did wrong.


This is the equation I got to get my answer:

(8x4)÷23+(9-7)=

32÷23+(9-7)=

32÷23+2=

32÷8+2=

4+2=

6

  2. WOW, NICE JOB! You really explained everything well and it is very clear. I really like the "To practice our knowledge, we were given equations to solve:" part. I wasn't expecting that. The equation you did was good, it doesn't repeat any numbers and it has everything in BEDMAS. That is exactly what I have on my notes too. Awesome scribe (:

  14. Fantastic job JB! In my opinion your scribe is the best one yet. :D Your scribe is explained well and easy to understand. I saw no mistakes and I like how you changed the colour at the beginning of the scribe.
    My answer for the equation is the same as yours.
    (8x4)÷23+(9-7)=

    32÷23+(9-7)=

    32÷23+2=

    32÷8+2=

    4+2=

    Great job!! :D :D

  15. Great job! Your explanation of what we did was very good! Your equation was correct. Here's how I did it:
    (1 to the exponent 2+3)/4x5+7-6
    (1+3)/4x5+7-6
    4/4x5+7-6
    1x5+7-6
    5+7-6
    12-6
    6
    Have a great day! :)
