Socrative’s Equation Editor allows teachers to enter multiple equation types (LaTeX, mhchem, and Physical Units) in question formats, multiple choice answer choices, and explanations.
Table of Contents
Inserting Equations
When creating or editing your quiz, go to the question you need and look for the Insert Formula button. Once opened, you can use your keyboard to start typing in the formula you need, and it'll automatically be formatted. Or you can copy the formula from another page and paste it in.
Supported Equation Types
The Equation Editor supports multiple equation types, so you can use the one you’re familiar with. You can use LaTeX, MathASCII, and mhchem (Chemical Equations).
Inserting Math Equations
To start an equation, use \
and some letters to see some suggestions:
Alternatively, you can click the keyboard button to open the virtual keyboard and look for specific symbols. If you know the keyboard shortcut, that works too (ex. try using Shift + 6 to start typing in exponents/superscripts).
When the formula is typed in, click the check mark icon to save it.
Inserting Chemical Equations
Chemical Equations have a descriptor to let the equation editor know your intent. To get started, write \ce{formulae}. The delimiter \ce{...}
is required since you can use mathematics delimiters for chemical formulas.
What's possible with Chemical Equations?
Formulae
Amounts
Equations
Charges
Stoichiometric numbers
Nuclides, isotopes
Reaction arrows
Parentheses, brackets, braces
Variables like x, n, 2n+1
Bonds
Addition compounds
Oxidation states
Equation operators
Unpaired electrons, radical dots
Krögervink notation(not supported for latex yet)

Inserting Physical Units
Physical Units have a descriptor to let the equation editor know your intent. To get started, write \pu{units}. The delimiter \pu{...}
is required since you can use mathematics and chemical delimiters in conjunction.

Inserting Greek characters
Just write \alpha
etc. You can insert Greek Characters in your equations (see examples). Spaces after a greek character are ignored. This is standard TeX behaviour. Insert {}
to get the desired output. Unfortunately, we do not support upright lowercase Greek characters.

Formatting your Equations
Inserting (italic) math
If you want to escape math mode and insert italics, you can do so by using $...$
.
Upright text
To keep your text upright, you can enclose the text with {...}
. With the same mechanism, you can escape the autocomplete equation, for instance, if you need a simple hyphen (that should not become a bond).
