Math Game~~~ (Can you solve the problem?)
Hey guys! I thought up an interesting game to play. Rules are this. I start with a very simple math equation. The person who solves it first adds onto the problem with one additional number. It can be anything in basic math ( +,  , X, /) You cannot use a calculator. Obviously I can't tell if you did or not, but for your own self respect try doing this without a calculator. It'll probably start of easy, but get progressively harder. Let's see how long this goes until no one can solve it anymore. hahaha Only 3 posts by the same user on the same page. Make sure to quote the equation so that people can see what they need to work with. Here's an example
(example: 1 + 1..... Someone solves =2 , that person adds 1 + 1 X 5, someone solves = 10...and the cycle continues)
Let the geekyness begin!

8 + 4 =?

I wish we can use algebra..
8+4+3/3 = ?
8 + 4 + 3/3 = 12 + 3/3 = 13
(8+4+3/3) / cos 78,6 = ?

(8+4+3/3) / cos 78.6 = 65.77
(8+4+3/3) / cos 78.6 (100)= ?
(8+4+3/3) / cos 78.6 (100)= ?
Re: Math Game~~~ (Can you solve the problem?)
(Actually (8 + 4 + (3 / 3)) / cos(78.6) = 13.0235791.)

And you say you calculated this by heart... I have serious doubts.

Honest to be ... I have my doubts too! But maybe we have some MATHS GENIUS around...you never know

I think I already sense the MATHE GENIUS here. I hate to say I'm not good at math just give me books and take me to a literature subject is enough for me. Waaa!

You dont have to be a genius to figure it out.

(8+4+3/3) / cos 78.6 (100) = 13 / 13.02*100 = 13 / 1302 = 0,009984
(8+4+3/3*pi) / cos 78.6 (100) = ??
(8+4+3/3*pi) / cos 78.6 (100) = ??

i'd just like to point out that 1 + 1 * 5 is 6 and not 10

((8 + 4 + ((3 / 3) * pi)) / cos(78.6)) * 100 = 1 516.90561
Sorry for change in symbols, it must be done for it to be correct.

And you calculated this without using a calculator... ??? I highly doubt it.

it's not really that difficult if you take it one step at a time
13 * pi is 13*3,14 which is 40,8
Divided by cos of 78,6 which is 13 which someone already said
So its 40,8 divided by (13*100) which is 1300
So basicall 40,8 divide by 1300 is 0,031

There is only 1 problem with that pi is NOT 3.14 and Im sure you know that very well and the result visible what I commented had a lot more digits as well.

Re: Math Game~~~ (Can you solve the problem?)
Yeah because he multiplied the whole number with 1300, i multiplied the number divided by with 1300(which is how you're supposed to do it unless theres parentasis around the whole thing). Example:
10/2*2 is equal to 10/4, but (10/2) * 4 is a completely different number.
And yeah pi might not be 3.14 exactly but it's a rounded up number that is commonly used when studying math.
10/2*2 is equal to 10/4, but (10/2) * 4 is a completely different number.

I meant with lots of digit red part 1 516.90561 and yes I know parenthesis makes a big difference but we were taught NEVER round up the value of pi because that changes the result. But I guess habits are different everywhere.
Im glad for everyone who can count ((8 + 4 + ((3 / 3) * pi)) / cos(78.6)) * 100 in their head and get such an answer as 1 516.90561. Good for them.
