// Create via a string
    BigInteger bi1 = new BigInteger("1234567890123456890");
    
    // Create via a long
    BigInteger bi2 = BigInteger.valueOf(123L);
    
    bi1 = bi1.add(bi2);
    bi1 = bi1.multiply(bi2);
    bi1 = bi1.subtract(bi2);
    bi1 = bi1.divide(bi2);
    bi1 = bi1.negate();
    int exponent = 2;
    bi1 = bi1.pow(exponent);
