# How I can introduce blanks in a mathematical formula?

##
Usually, in mathematical expressions we need introduce some blank spaces. For example, when we write #10 m# leaving a blank within number and unit, the script erases this blank space and the symbol of unit appears aside from number. There ara some way to do it?

I try to use quotes with a blank space in between, like #10" "m# , but then there are to much separation. Sometimes, I put the unit out of mathematical call, like this: #10# m, but then change the font and the result is unsightly...

Try using the format hashtag color(white)(0) hashtag and putting in as many 0s as you need

#### Explanation:

Try spacing using the following format:

hashtag color(white)(0) hashtag - and you can put in as many 0s as needed.

In practice, it looks like this:

10color(white)(0)m - no hashtags

~~~

10color(white)(000)m - no hashtags

~~~

And of course you can scale the characters within the brackets (I'm referring to the 0s) to whatever size you need.

Here's what you could do.

#### Explanation:

One quick way to tackle this problem is to use quote marks to enclose the number + unit.

For example, something like

without hashtag"10 m"

with hashtags

#"10 m"#

Another example would be

without hashtags3 xx "2 moles" = "6 moles"

with hashtags

#3 xx "2 moles" = "6 moles"#

This gets a bit tricky when you're dealing with fractions, square roots, exponents, and things of that nature.

For example, something like

without hashtagssqrt(2) xx "2 m" = "2sqrt(2) m"

with hashtags

#sqrt(2) xx "2 m" = "2sqrt(2) m"#

As you can see, the quote marks convert automatically convert anything that they enclose to *text*. In such cases, you can go

without hashtags"2 m" xx sqrt(2) = 2sqrt(2)" m"

with hashtags

#"2 m" xx sqrt(2) = 2sqrt(2)" m"#

That blank space added within the quote marks is enough to provide some separation.

Alternatively, you can use color(white)() to create spacing by adding *white characters*.

In this case, you'd have

without hashtags"2 m" xx sqrt(2) = 2sqrt(2)color(white)(.)"m"

with hashtags

#"2 m" xx sqrt(2) = 2sqrt(2)color(white)(.)"m"#

Here I used a white dot "." to create a bit of separation between the math string and the text.

As you would imagine, you can play around with the color(white)() function to create a whole bunch of cool stuff.

For example, you can have

with hashtags1 color(white)(a) 2 color(white)(aa) 3 color(white)(aaa) 4 color(white)(aaaa) 5

with hashtags

#1 color(white)(a) 2 color(white)(aa) 3 color(white)(aaa) 4 color(white)(aaaa) 5#

These are basically the main techniques we use to introduce blanks in math strings.
