# The calculator

This feature allows the user to manipulate their project inside MiningMath, enabling adjustments and new field creation. Figure 1 shows a general view of the calculator. On the left side we have the block parameters and on the right the calculator itself, where the calculation can be done.

To manipulate the calculator just insert a name for the new field, select the type of field (to know more about field types,), and build your expression. In case of a more complex expression, just mark the field “Logical Test” to enable conditional features.

• - : Subtraction

• * : Multiplication

• / : Division

• % : Modulus

• ** : Exponential

• // : Floor division

## Practical approach

To facilitate the understanding, let’s work on some examples. You can see below a generic math expression (left), and its equivalent written on MiningMath’s calculator (right)

$$(x^2)\times(\frac{y}{2}-1)$$ x**2*((y/2)-1)

## Adding a field without logical expression

Using an example of the Marvin’s Economic Value calculation, we are going to add a Block Tonnes field, as the figure 2:
