Anyone maths please?

hello!

I want to insert this equation to Excel:

I came up with this (obviously, P = I7 cell, etc)
=(I7*6*sqrt(J7)*(1.99-J7*(1-J7)*(2.145-3.93*J7+2.70*J7^2)))/(F7*sqrt(G7)*(1-2*J7)*(1-J7)^1.5)

What could be wrong in the above function?

Thanks!

The ^ was just an example...
Here's another possible issue

2.145-3.93*J7+2.70*J7^2

Using brackets to illustrate, this is the order that would be calculated
(2.145-(3.93*J7))+(2.70*(J7^2))

Is that the way you're expecting ?

Yes that's the order I am expecting, I will try to add more brackets.
How does it choose which brackets to go first? It calculates the most inner brackets towards the most outer?
