Order Of Operations

There are 4 operations:


1st. Brackets
2nd. Exponents
3rd. Divide or Multiply in order from left to right.
4th. Addition or Subtraction in order from left to right.

(6.4+120)x1.25=156.4

What sign goes where? +, /
5.2 / 4 + 2.1= 3.4
1.3+2.1=3.4

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.

I don't agree because the answer i got was 9.7. I think she added it wrong. i calculated 1.7+6 and it equaled 7.7 then i added 2 and i got 9.7

  4. Nice job Jomer, the picture was great and the video was helpful, it would've been better if there was as link.
    I don't agee with Annie because I added 1.7 + 6 = 7.7 and then added the 2 with the sum and it equalled to 9.7.

  6. Good job Jomer! I like the picture that you put and the colors that you used. But next time try to find a link.
    I agree with you because I added 2+6=8 and then 8+1.7=9.7

  11. Good Job Jomer, I suggest that next time try to find a link. I'm not sure I copied the problem right cause on mine I have 1.7+6\2=3.85. If it is 1.7+6+2=9.5 I agree with you.

  14. For homework the question was 1.7+6+2? I thought the question was 1.7+6÷2.
    However, when I calculated 1.7+6÷2, I got the answer 4.7.
    Then I went to my calculator to see if I was correct and typed the numbers down. But instead of typing them down how I did it on my paper (using the BEDMAS steps), I typed it "normally", from left to right, and got Annie's answer 3.85.
    So Annie is incorrect because she didn't go through the BEDMAS steps.
    However, I don't know if I wrote the wrong question down or if you did. So to determine if we had to ÷ or + 2, I will calculate 1.7+6+2 using the BEDMAS steps, and the "normal" way (starting from left, to right).
    If I don't get the answer 3.85 using both ways, then I think that means the proper question would have been 1.7+6÷2.

  15. Good Job Jomer! Nice picture but next time try to get a link. I also agree with you because 1+6+2=9+0.7=9.7

  17. I have calculated the question 1.7+6+2 using both ways. However, you couldn't have really calculated this question using the BEDMAS steps, because it only had one "operation". The only operation here was +, so this question turned out to be just a "normal" addition question. So what I did was just add the numbers together and got 9.7. Since the answer for both ways wasn't 3.85, then that determines that the proper question would have been 1.7+6÷2.

  18. I disagree because the answer Annie got was wrong because the right answer was more than 3.85. by the way, nice job with your post!!

  19. Good job Joemer! I really liked the picture and the video,Ryan i think your right i copied the same equation as you, so if i use BEDMAS I would divide 6 by 2 the quotient is 3 then i added 1.7 and the answer i got is 4.7 .

  20. Im not sure but, i think the question was 1.7+6 divided by 2, because if you were to solve that it would equal to annies answer which is 3.85

  21. Good Job Jomer. I think you did a great job.
    I also agree with you because 1+6+2=9+0.7=9.7
    the video was really helpful

  22. Everything was good. I liked how you got the adittion and subtration brother thing on the blog and the video was good too. I also belive that the answer is 9.7 because if you add the 1 and 6 together and I got 7 and then I put the 2.7 and got 9.7.

    P.S. Jomer, you have to make the I a capital when you write it.

  23. Great job Jomer! I really like your picture it was very creative. I do not agree with Annie because when I followed the BEDMAS steps I at least got more than 3.85 and I think she added the answer wrong. I did 1.7+6+2= 9.7
