It'd be easiest to go through the 6 possibilities one by one until you find the possibility that has the desired value 14. Looking at possibility #6: You've got 6 times (4-4+9), plus 3 added to this product. That comes out to 6 * (9) +3, or 57. Wrong. Do the same thing with the other 5 possibilities until you find the one that produces 14.
I think it's C.
Show me how you decided that. I need proof.
It was just a guess
Please, let's not deal in guesses. I'm here to help, but I help you find your own answers thru legitimate math.
C has the value 36, which is not correct.
I really wanna learn how to do it, But i'm also in a big hurry.
Can't do much about your being in a hurry. Sorry. choose one of the other answers, and we'll go through it together to see if it has the value 14.
Type it out here. Remember "order of operations? rules? Which operation would you do first in D?
D. 6 • (4 – 4 + 9) – 3 Evaluate the quantity within ( ). 4-4+9 = ?
Right. What's the next operation you must now perform? Mult. or subtraction?
right. Please do that multiplication now. When done, subtract 3 from your result.
So it's not D
My next guess is B
You're correct, but that's not 14. So, D is out. C is out. I'm going to leave y ou for a while; please do the other probelms. Seriously, seriously, please, please, do NOT guess. Guessing won't help you to understand this material. Write out B and decide which math operation should be done 1st, 2nd, 3rd, etc.
6 • 4 – [4 + (9 – 3)] which operation must be done first? second?
Anything within ( ) must be done first.
1. Parenthesees 2. Exponents 3. Multiplication 4. Division 5. Addition 6. Subtraction
Good. In 6 • 4 – [4 + (9 – 3)] which operation must be done first? second?
I said it. That's why I numbered it.
In 6 • 4 – [4 + (9 – 3)] you must do that (9-3) first. What is 9-3?
Then you have 6 • 4 – [4 + 6]. Which operation must you do first now?
Yes. 6 • 4 – 10 = ?
which op must you do first?
the answer is 14
What about it?
I asked y ou which operation you should do first. Which was that?
That's what the next step was
6 • 4 – 10 yes, mult. 6 by 4 first. You're correct. Nice work!
gotta get off the 'net. see y ou again! bye
