# How would you write Sc 45/21 in an answer on Socratic?

## I'm quite new to Socratic and I wasn't sure how to use both subscript and superscript in an answer. Sorry if its been posted in the wrong section.

Here's how you can do that.

#### Explanation:

The idea here is that you can add subscripts and superscripts by using the syntax

• without hashtags

"character" _"subscript" ^"superscript"

• with hasthags

$\text{character" _"subscript" ^"superscript}$

Keep in mind that the two must be added in this order, i.e. subscript first, superscript second.

So, for example, you can write things like

• without hashtags

x_1^2 + x_2^2 = "something"

• with hashtags

${x}_{1}^{2} + {x}_{2}^{2} = \text{something}$

Another example would be

• without hashtags

P_(x + y) ^ (a + b)

• with hashtags

${P}_{x + y}^{a + b}$

Now, to add subscripts and superscripts before a character, you can use something called a blanck character, which is simply two quote marks one after the other $\to$ ""

In your example, scandium-45 would be written like this

• without hashtags

""_21^45"Sc"

• with hashtags

$\text{_21^45"Sc}$

So basically you're attaching the subscript and the superscript to the blank character.

Another example would be

• without hashtags

""_(x + y)^(a + b)P

• with hashtags

""_(x + y)^(a + b)P
