That is fun, but shouldn't it be

√-1 2^3 ∑ π        ???

(  -1 not -2)  

La tua seconda ^ non ha senso.

Add 51/6 to both sides 

Start by adding 7 to both sides :)

The reason this logic works is that the 5 and the 7 both have the same place value.  They are both just one place behind the decimal point.  They are both in the tenths column.

Great work.

Standard form is the first answer.

I think the =0 one is general form :)

Volume of what?
