The "math/big" package in Go offers advanced mathematical operations for "big integers" that are not natively supported in the Go programming language. One of the primary functions offered by this package is "Add" which is used to perform addition on big integers.

Here are some code examples:

**Example 1:** Adding two big integers

In this example, we are creating two big integers "x" and "y" using the "big.NewInt()" function. We then create the third big integer "z" and use the "Add" function of the "math/big" package to add "x" and "y" together. Finally, we print the result to the console.

**Example 2:** Adding multiple big integers

Here are some code examples:

package main import ( "fmt" "math/big" ) func main() { x := big.NewInt(123456789) y := big.NewInt(987654321) z := new(big.Int).Add(x, y) fmt.Println(z) }

In this example, we are creating two big integers "x" and "y" using the "big.NewInt()" function. We then create the third big integer "z" and use the "Add" function of the "math/big" package to add "x" and "y" together. Finally, we print the result to the console.

package main import ( "fmt" "math/big" ) func main() { numbers := []*big.Int{ big.NewInt(12345), big.NewInt(54321), big.NewInt(67890), big.NewInt(98765), } sum := big.NewInt(0) for _, n := range numbers { sum = sum.Add(sum, n) } fmt.Println(sum) }In this example, we have an array of big integers "numbers" and we want to add them all together. We create a big integer "sum" and initialize it to 0. We then loop through the "numbers" array and use the "Add" function to add each element of the array to the "sum" variable. Finally, we print the result to the console. In conclusion, the "math/big" package in Go is a powerful and essential library for dealing with big integers in Go. It provides many useful functions, such as the "Add" function, which makes working with big numbers much easier.
