6 - 1 x 0 + 2/2 = ?


Is the answer 1?

Or is it 7?

Or is it some other number?

1 is the answer. So why is this equation even up as a thread? what meaning is behind it?

To 12:01PM ~~ Stop being annoyed & explain how you arrived at that answer.

According to the PEMDAS method (order of operations) the answer should be 7. Multiplication and division precede addition and subtraction.
6-(1 times 0) + 1

The answer is 7.
basic math, order of operations () * / + -

so 1*0 = 0 and 2/2 = 1
6 - 0 + 1 = 7

Scats,
Sorry if I spammed my last post... I wasn't sure if it accepted the password for making the post.

Please feel free to delete any duplicates.

The key is the Order of Mathematical Operations which requires that multiplication be done first. This assumes that brackets were not used to facilitate the proper order of operations.
Thus 1 X 0 is solved first and yields 0. Then 2/2 = 1 as division accompanies multiplication in the order. Now we have 6-0+1 = 7.
However if 6-1X0+2 were bracketed then it would be solved first and then that result divided by 2 as the denominator would be "2" below the division "line" and the entire bracketed numbers would be the numerator.
I have no idea how the "new math" works.

As I learned math (albeit in the olden days of the 60's),
6-1 = 5 but now when you multiply the 5 by 0 the sub answer=0 which is now being added to the fraction 2/2 which = one.
So SCATS, I will bite, ok just nibble, what's the purpose behind this question?

7, the multiplication and division come first, left to right.That gives you 6-0+1=7.

OK Scats, here is my version of the answer. I learned algebra in the early 70's, so what do I know with the new math concepts. As you have presented the problem :
6-1 = 5, now 5 times 0 =0, with the sub answer being added to the fractional equivalent of 1, thereby the answer is 1.

BUT, if you had put parentheses around the 1*0, so the equation reads like this: 6-(1*0) +2/2=, then I was taught to solve within the parentheses first, then complete the equation, which would be 6-0 +1 = 7.
So, whats the back story on this??? Keep up the good job on this blog, you are my secret hero.

This problem is currently being plastered all over FacePlace!

The answer is an obvious SEVEN (7). Follow the "order of operations"... do all the multiplication and division first, left to right, then go back and do the remaining addition and subtraction.

You're welcome from a Greece math teacher!!!

To 1:20PM ~~ No problemo ;)

To 1:30PM ~~ No brackets were used or they would have been posted and ... The "new math" doesn't work!! lol

To 1:46PM ~~ Since Greece schools start LAST, thought I'd give teachers, parents and other admirers an opportunity to warm up their noggin's with this equation I saw on FB this morning.

To 1:56PM ~~ Your explanation is too general, you loose 50% credit ;)

Answer- 23
I feel good about the answer being 23 and since my self esteem is the primary function of math class 23 is the right answer.

Eureeka who sits to my right answered 11 and he's right too.

Can I supersize that for you?

Do I "loose" it? Or do I "lose" it? :-)

I could have predicted you would NEVER give any Greece teacher full credit for ANYTHING!

To 4:19PM ~~ If I weren't so darned predictable, would you still like me so much? lol

I also get 7 for an answer using the order of operations (pemdas). Greece Arcadia grad 1983. I found out 4 years ago when I returned to college for an advanced degree how much I learned there!

hmmm... 51 years old and the answer is still 7, as it was when I was 12. My 21 year old confirms it's 7 for him, too. Math is math. Science is science, too, except for at some places in Greece where the Earth is 6000 years old and the dinosaurs perished because they were too big for the Ark.
