Subindices in answers

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

Example 1

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

Using Ideal gas law, $fraction numerator P subscript 1 times V subscript 1 over denominator T subscript 1 end fraction equals fraction numerator P subscript 2 times V subscript 2 over denominator T subscript 2 end fraction$ , so the answer will be $V subscript 2 equals fraction numerator P subscript 1 times V subscript 1 times T subscript 2 over denominator T subscript 1 times P subscript 2 end fraction$

As usually, equivalent formats are marked as correct

Example 2

Imagine this question: Compute the determinant of the following matrix

$open parentheses table row cell a subscript 1 end cell 1 2 row 3 cell a subscript 2 end cell cell negative 1 end cell row cell negative 2 end cell cell a subscript 3 end cell cell a subscript 4 end cell end table close parentheses$

The algorithm will be
