Floats not being added to other floats?

Hi

I'm trying to build a script that generates hexagons with the click of a button. But whenever they spawn all of them are in the wrong x position because a float isn't being added in my script. I included the relevant part of my script.

The problem is with the lines that say "xPosition = xBase * 1732051 / 1000000 + 1732051 / 1000000 / 2;"

For some reason it will multiply 1732051 / 1000000 to the x base but not add the second part. I tried making a public variable/float that was equal to that number and adding that and I also tested multiplying it but for some reason unity registers it as a zero.

I really don't know what to do here none of the other answers really covered this particular issue. Please help
