An excellent answer anonymous  

This might be easier Tetration

(x-2)/(x+4)-5/6=0 

$$\frac{x-2}{x+4}=\frac{5}{6}$$

 (You should be aware that x cannot equal -4)

 Multiply both sides by 6(x+4)  That will get rid of all the fractions. 

6(x-2)=5(x+4)

6x-12=5x+20

x=32

7*(-4)^3+2/(-4)^2

=7*-64+2/16

=-448+1/8

=-447 and 7/8

If you mean

26,000*(1+(0.043)*(5/3))

you can just type it into the calc on the home page.  :)

Don't do that Rosala that would be terrible - talk to me please   

Well now aren't we in a narky, playful mood today :))

You made me giggle Rosala.  Thank you :)

We  got different answers Rosala.

Can you work out who got what wrong?

2*(x+4)-((1-(3*x))^2)

$$\\(1-(3*x))^2\\
=(1-3x)^2\\
=1-6x+9x^2\\$$

2(x+4)-(1-6x+9x²)

=2x+8-1+6x-9x²

= -9x²+8x+7
