Evaluating Formulas in Go

To evaluate mathematical formulas in Go, it's recommended to use an external package that provides pre-defined functions and operators. One popular option is govaluate:

Installing govaluate:
```
go get github.com/Knetic/govaluate
```

Formula Evaluation:

expression, err := govaluate.NewEvaluableExpression("(x + 2) / 10")

parameters := make(map[string]interface{}, 8)
parameters["x"] = 8

result, err := expression.Evaluate(parameters)

In the above example:

NewEvaluableExpression: Creates an instance of EvaluableExpression that represents the formula.
parameters: A map that specifies the values to be used for the variables in the formula.
Evaluate: Evaluates the formula using the specified parameters and returns the result as a float64.
