This is gonna be a strange one basically you post a maths question and the next person posts the answer and a new question

And if you dont like maths then dont post in this thread :approve:

(oh and math wizzes go easy on us)

First an easy one - 9*9

* = times symbol

CoachNH

16x^2+4x+2
Solve for X

justpaul205

x = (-4 +/- sqrt(16-112))/32

its a non-real answer.

hmmmmmmm...

y = sin(x) + tan(x)

find y'

fishwood

Well this is living proof that no one likes maths (well two peaple do)

Wow, it's been forever since I did calculus. At least a few years.

Without looking it up, isn't the prime of sin(x) = cos(x) .. and tan(x)= sin (x) /cos (x) + cos(x)/sin(x). Like I said.. it's been a while, but I didn't look at anything up - so yay if I got somewhat right!

As for a math question, how about a word problem. A $10.00 item is on sale for half-off. At the register, an additional 25% is taken off the sale price. What's the final price of the item, and what's the total % discount?

RHC-NET

final price $2.50, discount of 75% (just a guess, im prepared to be humiliated as my maths skills are none existant and i used my X5 as a calculator)

Rob

AnnamariaNJ

is it $2.50 and 75% off?

It's $3.75 or 62.5% off

Sales prices is $5.

25% off sales prices is $1.25 discount

$5 - $1.25 = $3.75

RHC-NET

im hoping since im not the only one who came up with that answer, it proves im not a dunce

AnnamariaNJ

hey, I didn't use anything but my head, and it would take ALOT more than that to make me feel like a dunce,...please give yourself more credit than that, this is ALL for fun! :approve:

forkyfork

It's a commonly missed math problem.. which is why I asked it.

For an ultra nerdy question - what's 8 in base 7 (Yes, base 7 exists).

If you want a hint, it's the same answer as 7 in base 6!

11
And 3 in base 2 (binary) is also 11

Rock on.

Actually any n+1 in base n is 11

just as any n in base n is 10.

Yay for math!

jpmarth

What is the highest number in terms of "n"?

Well...any one?
