There are a LOT OF GOOD YOU TUBES ON THIS TOPIC. 

1 plus 1 divided by 2 time 600

Technically, using PEDMAS  or BODMAS  or whatever your country calls it, this is the correct answer.

\(1+1\div2\times 600\\ =1+0.5\times 600\\ =1+300\\ =301\)

1)  Fun on the forum         

What are you on about !

(1/8) to the power of 1/3

\(=\sqrt[3]{\frac{1}{8}}\\ =\frac{\sqrt[3]{1}}{\sqrt[3]8}\\ =\frac{1}{2}\)

The button for it on the web2.0calc is      x^y

^{If you are using the input bar then use the symbol   ^}

We already answered this for you a day or so ago.

If you were a member you would be able to find it easily. It would be automatically be included in your watchlist!

So join up!  And then you will not feel the need to waste out time by asking the same question twice!

5sin(x+x)=4

Find solutions and round to two decimal place

sin(2x)=0.8

2x=asin(0.8)

2x= 53.13,   180-53.13,    360+53.12,     540-53.13

x =    26.57,      63.44,             206.57,          243.43    degrees

These are all the answers between 0 and 360 degrees.

That is some good forensic maths there Heureka       

(-7.9)+2.0+(-3.3)

=  -7.9 + 2.0  -3.3

-7.9+2.0-3.3 = -9.2     I used the forum calculator.
