# Subindices in answers

Now, WirisQuizzes allows answers with subindices so you can ask even more questions. For instance, a common question about chemistry or symbolic maths is possible.

## Example 1

Consider the following problem about chemistry: A perfect gas at ${T}_{1}$ K and ${P}_{1}$ atm of pressure occupy ${V}_{1}$ l in volume. What volume will the same gas occupy at ${T}_{2}$ K and ${P}_{2}$ atm of pressure?

Using Ideal gas law, $\frac{{P}_{1}\xb7{V}_{1}}{{T}_{1}}=\frac{{P}_{2}\xb7{V}_{2}}{{T}_{2}}$, so the answer will be ${V}_{2}=\frac{{P}_{1}\xb7{V}_{1}\xb7{T}_{2}}{{T}_{1}\xb7{P}_{2}}$

As usually, equivalent formats are marked as correct

## Example 2

Imagine this question: Compute the determinant of the following matrix $\left(\begin{array}{ccc}{a}_{1}& 1& 2\\ 3& {a}_{2}& -1\\ -2& {a}_{3}& {a}_{4}\end{array}\right)$. The algorithm will be

The *Correct answer* field will look like

So the solution will be
