3+3*3-3+3=0

If you got 12 its wrong because

Multiplying 3*3 is a wrong step to solving equation above

What affects +3 must affect -3

So putting (3*3) ain't good

Which is obviously wrong
So for duded with 12 calculators and mathematical apps ain't good for you.

if our educational system is wrong. then you are definately part of failures. the answer is 6. ask your younger ones in ss3 to solve it for you.

you should weep for yourself.


quote author=petikal post=36825119]I weep for our academic system... actually, no, our academic system is better than this! I weep for the ignorant ones blindly insisting that they are right to something this simple.

It's laughable to say Google can't do BODMAS when you have no idea the brains behind the search engine called "Google". These folks employ the brightest researchers in their field to solve the most complex/abstract problems, and BODMAS is the minutest of those.

If you're going to use BODMAS, apply it properly, and don't negate other mathematical rules.

-A+A is ALWAYS zero. Applying brackets doesn't change that.

The answer here is 12.[/quote]

you are not mathematically inclined too. the answer is 6. ask your younger ones at home

Datanet:



no man. you placed the parentheses wrong.

multiplication comes first so it should be
3 + (3 * 3) - 3 + 3

Then addition

(3 + 9) - (3 + 3)

before subtraction

12 - 6 = 6 qed

So when multiplying 3 by +3 it doesn't affect -3 is that what you are implying?

Read more on quadratics it will help you.

Datanet:
3 + 3 X 3 - 3 + 3

The answer is 6. Use BODMAS.

bracket of Division. multiplication. addition and substraction.

in tht order.

1. Division = No division in the equation so skip tht.

2. Multiplication = only multiply the numbers connected to it. that is 3 x 3. ignore the others.

therefore you have 3 + 9 - 3 + 3 left

3. Addition = now do only numbers connected to addition sign. tht is 3 + 9 and also 3 + 3

therefore you have 12 - 6 left

4. Subtraction = subtract numbers
12 - 6 = 6. qed

YOUR TEACHER DID NOT TEACH YOU IN SCHOOL THAT YOU SHOULD NEVER LEAVE THE MINUS SIGN OUT WHILE CALCULATING? YOU SAID 12-3+3=12-6? CHAI! NA WA FOR YOU O. DO YOU REMEMBER THE SET THEORY? WE USE TO HAVE SOMETHING LIKE 12-x+x+10-x=universal set. why didnt u get 12-2x+10-x=22-3x at the left hand side? I tot u normly say -x cancels +x and then get 22-x as ur left side part of the equation. so tel me why ur -3 didnt cancl +3 in 12-3+3 you got?

Pls simplify this equation for me; x+3x-3+x where x=3. Pls collect all the like terms collectable before insertin d valu of x into the equation.

hoping to engage you in a meaningful discussion

If you are told to calculate the expression 24 + 6 / 3 * 5 * 2^3 - 9, what will be your answer?

Datanet:
...therefore you have 3 + 9 - 3 + 3 left

3. Addition = now do only numbers connected to addition sign. tht is 3 + 9 and also 3 + 3

therefore you have 12 - 6 left

4. Subtraction = subtract numbers
12 - 6 = 6. qed

So, by YOUR 3rd rule: 3 + 9 - 3 + 3 => 3+9 and 3+3??

Don't you see the mistake there? How did -3+3 become 3+3?

Again, when students make silly mistakes like this, they're to blame, not the academic system.

the answer is still 6

minus sign is only impacted in a multiplication scenario.

like -3 * 3 = - 9

how when applying bodmas you only work with numbers next to the sign in question.

hope this helps.

I beg wots d ans op? Cos mine is 6 bodmas levels.

yes. it does not affect the minus sign because the multiplication sign is between the 3 * 3. and multiplication comes first before addition and subtraction.

Solving equation
3+3*3-3+3=?

(3+3) * (3-3) + 3= 0

(6) * (0) + 3 = 0

0 + 3 = 3

Adding brackets doesn't alter the equation because its like writing

[+3+3*3-3+3]=0

Very wrong sir.... PEMDAS OR BODMAS the answer is the same. Your solution is like saying x + x^2 - x = (x+x)*(x-x) do you now see that the bracket you introduced altered the original equation? The answer is 12 sir, sit down and look at it properly. God bless us

Please stop the silliness, the (-) came after the multiplication, and is a property of the value 3. Hence, the computation (-3)+3 is zero.

bodmas requires that you treat addition before subtraction.

so for a scenario of
3 + 9 - 3 + 3

only select numbers next to addition sign and ignore others.

so to make it clearly using parentheses it would be
(3 + 9) - (3 + 3)

those are the numbers closest to the addition sign before you ca then treat subtraction

hope this helps

Now that's a beautiful observation, I really appreciate but

I saw the below equation on First Bank BBM channel and what i saw with great dismay was the poor answers people were writing. Seriously our arithmetical knowledge needs to be awaken because i can't see a nation developing with poor analytical skills especially with simple equation.



So Nairaland members lets see those with good knowledge of arithmetic and those who will embarrass their parents.

@datanet
Even though A for addition is in PEMDAS/BODMAS before S for subtraction, these two operations also have the same priority. You look for these last two operations from left to right and complete them in that order.
I think we should all have a heart to learn...
It just hurts me seeing people doing something wrong and are bent on it

the computation

- 3 + 3 = 0 is correct only if this is the only equation we have

however the equation is

3 + 9 - 3 + 3 you must therefore apply BODMAS

hence. addition takes priority after you hav initially done 3 * 3.

hope this helps

petikal:

For those still doubting, I applied BODMAS and got 12, I applied real life scenarios and got 12.
Ok, if you can't do any of the 2 I mentioned above, then ask google
And if you're lazy to ask google, well I've helped you and below is the screenshot of google's answer.

No. Respectfully, your application of parenthesis is incorrect. Have you done quadratic equations before? What happens when you remove brackets following a negative sign? The (+-) signs that were inside change.

-(3+3) is equal to -1(3+3), which is equal to -3-3. The signs change. Don't apply BODMAS while negating other mathematical rules. And please stop saying "hope this helps". I've taught university level Calculus; this is very elementary and the argument is silly.

good point. DAGR8

i missed out on the left tto right rule.

you are right..

at this point.

3 + 9 - 3 + 3. the left to right rule should apply.

ao the correct answer is 12.

Let's for a second forget about BODMAS. I'm not about to lecture you; I just want you to reason with me. The question is (3+3*3-3+3)? Every number there with either + or - can move around but the exemption is (+3*3) . One can't move the +3 from its coleague *3 , they have formed a bond ( I think that's even why mathematicians brought the idea of BODMAS but if we all understand how NUMBERS work, we don't need BODMAS) that can't be broken easily. So, what u do is since (+3*3) have formed a bond, you tackle it first which equates to (+9). Now, You have removed the only sign (*) that is a problem to both - and + . You can now move them around as u wish i.e 3+9-3+3 or 3-3+9+3 or 9-3+3+3 or -3+3+3+9 . All must give 12. Reason with me that's all I ask.

yes. thats correct.

once you treat the 3 * 3.

every other one can be moved around.

you are right. its 12.
