does the order of operation require parentheses..... no. just makes it so you don't need to look at the equation.

Yup

 

[adsm08]

Any number times 0 is 0.

Yup, and since order of operations is parenthesis, multiply/divide, and then add or subtract, all the "x 0" does is remove the last 5, the rest of the equation stands as is.

P.E.M.D.A.S=order of operations.


Whew good thing I just graduated a year ago....

As a I am a lover of math, trigonometry, calculus and pythagoras theories there is no reason not to love any math puzzle.

Just following BEDMAS order of operation, you multiply the 5x0 first, so that the equation changes to:

5 + 5 + 5 - 5 + 5 + 5 - 5 + 0 = ?

The final answer is then 15

Loved it. I solved it first. Anymore neat math puzzles, Bro?

Hmm never learned BEDMAS (nevada edjumucation) Whats that stand for?

 

[adsm08]

BEMDAS is the normal order of operations except you start with the Bro-renthases.

Holy shit thats funny.

LOL - Thanks for the laugh Adsm!

That equation reminds me that I only do basic math most of the time. I estimate stuff for work all the time, but it doesn't ever make my melon smoke.

Sorry if I got you confused. You are right about PEDMAS. As you know there are acronyms to help us remember how to perform a set of procedure in math. BEDMAS or PEDMAS is one of them. BEDMAS is an acronym to help us remember an order of operations in algebra basics.

Pretty close, Bro....but no cigar.....lol

 

[doorgunner]

5 + 5 + 5 - 5 + 5 + 5 - 5 + 5 x 0 = ?

if you get this wrong politely remove yourself from the gene pool.

Reminds me of a war story.....
5NVA+5NVA+5NVA-5NVA leaves 10NVA+5NVA+5NVA-5NVA leaves 15NVA+5NVA leaves 20NVAx0ammunition leaves 20NVA.......

right answer/wrong decade

It's been 53 years since I had Algebra so I'm a little rusty there. lol

Here's another math situation.

Ever wonder about those people who say they are giving more than 100%?
*
We have all been to those meetings where someone wants you to give over
100%.

How about achieving 103%?

What makes up 100% in
life?

Here's a little mathematical formula that might help
you answer these questions:

If:
A B C D E F G H I J K L M N O P Q R S T U V W X YZ

is represented as:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26.

Then:

H-A-R-D-W-O-R-K
8+1+18+4+23+15+18+11 =
98%

K-N-O-W-L-E-D-G-E
11+14+15+23+12+5+4+7+5 =96%

A-T-T-I-T-U-D-E
1+20+20+9+20+21+4+5
= 100%

But,

B-U-L-L-S-H-I-T
2+21+12+12+19+8+9+20
= 103%

AND, look how far ass kissing will take you.

A-S-S-K-I-S-S-I-N-G
1+19+19+11+9+19+19+9+
14+7 = 118%

So, one can conclude with mathematical certainty,
that while Hard work andKnowledge will get you close, and Attitude will get you there, its the Bullsh!t and Ass Kissingthat will put you over the top.




Now you know why some people are where they are!

Sounds like a great life lesson lol.

Ah,,,, what equation? That is merely a string of operations.

OK, this isn't a puzzle but rather a problem that needs solved correctly. It's an actual set of numbers from an engine.

the basic situation is how much pressure is exerted on a piston stop bracket when torquing the crankshaft bolt.



Data facts: stroke of crankshaft = 80mm/3.1496"
force applied to crankshaft = 200 Lbs/ft

there are 3 seperate stops applied to the piston, (hence this is actually 3 problems).




the first stop would contact & halt the piston when the crank is at 90 degrees before top-dead-center.


the second at 45 degrees before TDC



the third at 10 degrees before TDC



That 3rd stop is the one I'm really interested in.

BONUS, a fourth stop is applied that has the piston stopped 1/2" below TDC, not sure on the crank angle, only the distance from TDC is known.


I would expect the last one to be in the Thousands of pounds.

My math is a bit rusty, How rusty? Back when I was in HS we used slide rules in chemistry class.
