Oh, hey, look at Mr. Fancypants! "My tent cost a three digit number!"

I bet you even have a pump for your *wheez* air *cough* mattress!

Kids these days.

Google it. Some people post their designs online.

I recommend The Slingshot channel

I don't do air mattresses, they have a habit of deflating during the night.

I use a camp cot with a memory foam pad, sheets, blankets and a comforter.

There is a string that goes into the channel between the rows of pegs which holds the back end of each rubber band. As the small smooth cylinder closer to the camera is rotated counter-clockwise from the camera's POV, it pulls the string which rotates the larger cylinder holding the rubber bands also counter-clockwise. The string pulls up the back end of the rubber band thus launching it.

Hmm--this a right-handed rubber band machine gun, meaning that you must hold the gun with the stock against your left shoulder and holding the bottom of the launch barrel with your left hand.

everybody will get a participation ribbon too

Common core didn't change the order of operations.

That's also a photoshop because powerpoint in fullscreen mode hides the menu bar and those kids are too young for multiplication anyway. (Order of operations is middle school.)

See, proof the old Dark Ages way of teaching math is a total failure!

that's a talented troll, we were pretty upset

maybe that's why i can't make sense of it; half the images could be fake

It has nothing to do with common core whatsoever - something it has in common with every common core meme.

The problem is about whether or not the / operator implicitly puts everything after it in parentheses. That is, 20/(5(2*2)) or 20÷5(2*2).

ahhh ... i only read it as the latter

Troll math for Order of Operations nazis. (Like grammar nazis, but they did STEM so they are superior to normal grammar nazis because they will be able to pay off their student loans.)

Has to do with this sort of thing.



The "proper" way to write it that would get you 16 would be:

20 ÷ 5 x (2 x 2) - with an operator in between each value.

The "proper" way to write it and get 1 would be:

20 ÷ (5 * (2 * 2))

When you omit the 'x' between the 5 and the (2x2) it becomes slightly ambiguous. Does the lack of a multiplication sign between the '5' and the '(2*2)' mean that the 5 is part of that expression or not?

20
_____
5(2*2)

vs.

20
__ x (2*2)
5

You do better when you're not intentionally trying.
Sloppy math happens in lots of places.

See the black string? Note how its wrapped around the barrel and underneath each of the rubber bands. As the wooden dowel in the foreground rotates, it causes the barrel to rotate and when the string lifts off the end of the rubber band, it fires. Pulling the trigger probably engages a ratchet that turns that dowel. If you want full auto instead, have a clockspring engage a gear to drive that dowel and change the trigger to start and stop the clockspring rotation.

Yeah, that's not how common core works.

Edit: I see dv already covered it.

Old joke but still a good one

odd, i thought there was a glut of gas on the market ... i wouldn't have thought the economics would support a project like thsi

Larger usually means more efficient, which is useful when margins are squeezed. This even happens in life. Kodiak bears are larger than Grizzlies.

wat

ah, ok ... turns out the expected huge production of gas in north america is taking longer to hit the market than expected, so the market's still tight and will remain so for awhile now

so if this offshore project can get online before the north american exports hit their stride, it can have direct access to the desirable asian market

So the first self-driving car may be available in five years. Awesome Google.
