The Math Game

That's if you follow the MDAS rule

Multiply
Divide
Add
Subtract

So let me tell you the story behind this equation:

Back when I was in High school (1992-96), We used to play a game in math class similar to this here game I posted.
In it we chose numbers between 1-9 (just like here) whick correspond to a "group" number, each group was made up of 3 people per team.

The Idea was to "rapidly shout out" an equation aimed at an enemy team,then that team ONLY has 5 seconds to react or solve the equation, the team who "misses" their "call" is out then so on.

In one occasion I shouted " 4 plus 4 minus 4 times 4 divided by 4!"

Well yeah the answer is 4 that is if you listen to the "order by which I shouted"

So again:

4 plus 4 minus 4 times 4 divided by 4

4 plus 4= 8
minus 4= 4
times 4= 16
divided by 4 =4

 

That equation would be written as :

(((4 + 4)- 4)* 4)/ 4

The MDAS or BMDAS or whatever else people add to it....(B being Brackets/Parentheses)
is always used....

The problems lies with the ambiguous nature of speech...
BMDAS does not apply to equations when spoken...

4 *pause* plus 4 *pause* minus 4 *pause* multiplyed by 4 *pause* divided by 4...
when you say this to someone, they are calculating throughout the equation....
and thus the equation yields the answer 4...

4,
+ 4, (= 8)
- 4, (= 4)
* 4, (= 16)
/4 (=4)

Try to remember writing mathematical equations is different to speaking them...

 

Okay, so ill make one this time....It wont be bad like last time (sorry about that)

3+4

I was taught PEMDAS, which includes parentheses and exponents.

Exponents...I knew something was missing..
Parentheses = Brackets
PEMDAS = BEMDAS

Legend's post was the answer....
anyways

[(2^3+2^4-2^2)/2]+(-13)+1x=1

Find X!

No algebra. Disqualified.

1 x 1 - 1 / 1 + 1 + 1 / 1 x 1 + 1 x 1 / 1 = ?

Remember your order of operations!

 

... it is algebra isn't it...

Next person get the new equation, I don't want to post it

 

v(Dude... you didnt even have to post the equation...)

 

... answer is 3.

1+2-3+4-5+6-7+8-9+10=
