is it 2+-2 because that equals 0

1+1 = the world

Do you mean 2-2?

My teacher says its 0, I don't get it...

Its 4 you idiot... GG Dummy

1+1 is 11 or 21

I'm positive it's nothing else but 4

I'm sure its 4

2+2 is 22

How old are you?

ITS FOUR!!!!

4

2+2 is 22

First find Lowest Common Denominator.

Then add numerator.

Then Simplify.

e.g.

1/3 + 2/4

LCD 

3,6,9,12

4,8,12

Its 12!

So, 

1/12 + 2/12 

Now it gets easier.

1+2 =3 

3/12 

Simplifed = divide by 3 

Which is 1/4

Using those steps, (if you want) try to do :

3/4 + 6/5

0.44/1 . 

Times by 100 (theres 2 digit on 0.44 so 10*10 =100)

44/100

Now simplify it

Divide both by 22 so 44/66 = 2/3 as 44/22 = 2 and 66/22 = 3

2+2 is either 4 or...Fish

it is 2 (answer)

Theres loads of way as algebra, can be put into different ways. But heres a simple one.

x + 60 = 110

If we do the inverse, 110-60=50 

x=50

50+60=110

Wow, a new record, 16 points!!!

Nauseated, if you continue these 'Amazing Combacks' you could probably tie points with Melody!

how many years will it take to double $1000 at 20% interest.

$$\\2000=1000(1.2)^n\\
2=1.2^n\\
log2=log(1.2^n)\\
log2=nlog1.2\\
n=log2\div log 1.2$$

$${\frac{{log}_{10}\left({\mathtt{2}}\right)}{{log}_{10}\left({\mathtt{1.2}}\right)}} = {\mathtt{3.801\: \!784\: \!016\: \!923\: \!930\: \!7}}$$

almost 4 years.

its o and it is easy took me about 3 seconds

ok sorry            

18 r s to the 0'th power t to 9th power over.

6 r to the 8th s to seventh and t to the fourth.

$$\\\dfrac{18rs^0t^9 }{ 6r^8s^7t^4}\\\\

=\dfrac{3rt^9 }{ r^8s^7t^4}\\\\

=\dfrac{3t^{9-4} }{ r^{8-1}s^7}\\\\

=\dfrac{3t^{5} }{ r^{7}s^7}\\\\$$

Hi Natthada,

Can you use the [calculation] button and type this calculation straight onto the forum please so that we can see the 'working' please ? 

Because of pineapples.
