Good afternoon all,

I understand that "X倍の" means "X times of", however sometimes I see the phrase
"X倍もの" and I was wondering what it means.

For example, in the sentence:

> 人間の脳には、約140億の神経細胞と、その10倍もの、神経細胞を支持する細胞があります。

I was wondering what's the function of the "も" in "10倍もの" ?

Or rather, what's the difference between the above sentence and this sentence
(same sentence but omitting the "も"):

> 人間の脳には、約140億の神経細胞と、その10倍の、神経細胞を支持する細胞があります。

"10倍もの" vs "10倍の"
Try looking at the sentence without that その10倍もの part, first:

```

    人間の脳には、約140億の神経細胞と神経細胞を支持する細胞があります。
    
```

The sentence seems to be focusing on the following types of cells in the human
brain:  
`神経細胞` and `神経細胞を支持する細胞`

But the first type of cell has a numerical amount given: `約140億の`.

When the `その10倍もの` part is added before `神経細胞を支持する細胞`, it seems to be building
off of the numerical amount of the first type of cell (the 140億,) and using も
as a way to say:

> " **as much as** 10 times the amount _(of the previously-written 140億
> amount)_ "

Basically, without も, the sentence might not have the same emphasis (regarding
the massive amount of "support nerve cells" in the human brain.)
