I am glad you like it. I don't know if it is available for iPhones :/

Pi is the ratio of a circle's circumference to its diameter. There are an infinite number of digits of pi, more than 10 trillion digits are known.

Pi equals approximately 3.14 

pi also equals delicious foods

a2 + b2 = c2  Where a and b are the two sides next to the right angle, and c is the longest side opposite the right angle (hypotenuse). If you want to find the length of side a or b, simply rearrange the formula...             a2 = c2 - b2  or  b2 = c2 - a2. 

Your welcome, Queen.

also, thx titanium.

omg. 9 likes. Everyone really wants to see my face lol.

Dividing a number is like multiplying the reciprocal of it. The reciprocal of 1/4 is 4, so 8 times 4 is 32. 8/(1/4)=32.

my army may be wrong, i may be wrong, and also, you're wrong.

my army isn't wrong

everyone in the forums is wrong

we all make little errors from time to time, so next time you use the word wrong, think twice

also, if that wasn't enough, my army may be wrong, but my army is undestructable and highly advanced compared to yours

also dont judge me just because your a god and i'm an emporor, you chose me to rule the pacific part of the forums, so if i am wrong then you are wrong as well

how is that, mr.immortal?

For expanding two binomials, you can use the FOIL method. (F: First terms, O: Outer terms, I: Inner terms, L: Last terms)

4x^2-64x+4x-64=4x^2-60x-64.

hey anonymous, i may be wrong, but at least I tell people who I am, unlike you who has to be anonymous sitting in front of a computer taking a p**s!

how's that, mr.unperfect?

One dozen is 12

Let your current age be  A .....so  your age one year from now is A + 1 and one year ago was A- 1   ....and we have

For the first part, we have

(4/5)(A) > (3/4)(A + 1)    multiply through by the common denominator of 4 and 5, i.e., 20

16A > 15(A + 1)   simplify

16A > 15A + 15    subtract 15A from both sides

A > 15

And for the second part, we have

(4/5)A > (5/6)(A - 1)     multiply through by the common denominator of 5 and 6, i.e., 30

24A > 25(A - 1)      simplify

24A > 25A - 25      add 25 to both sides and subtract 24A from both sides

25 > A      or, expressed another way.....

A < 25

So.....using both solutions, we have

15 < A < 25       {your possible age is greater than 15 but less than 25 }

8x1/4=8x.25    

.25x8=

Yes I just wanted to see that if i typed in German if anyone would understand.

Can be found from the calculator here using the syntax: log(5,2)

$${{log}}_{{\mathtt{2}}}{\left({\mathtt{5}}\right)} = {\mathtt{2.321\: \!928\: \!094\: \!887\: \!362}}$$

                                                                    A + P + K = 18      ...(1)

A = K/2          Multiply both sides by 2 to get  2A = K                   ...(2)

                                                                    P = (A + K)/2        ...(3)

Replace K in (1) and (3) using (2)

A + P + 2A = 18      or    3A + P = 18             ...(4)

P = (A + 2A)/2        or    P = 3A/2                  ...(5)

Replace P in (4) using (5)

3A + 3A/2 = 18      or 9A/2 = 18   so  9A = 36  or A = 4

Use A in (5) to get P = 3*4/2 or P = 6

Use A in (2) to get K = 2*4 or K = 8

Anders is 4, Petra is 6, Karin is 8

10% of 39 is 39*10/100 = 3.9, so if this is subtracted from 39 you have 39 - 3.9 = 35.1
