How do I do math operation for BigDecimal?

package org.kodejava.example.math;

import java.math.BigDecimal;

public class BigDecimalOperation {
    public static void main(String[] args) {
        BigDecimal decimalA = new BigDecimal("98765432123456789");
        BigDecimal decimalB = new BigDecimal("10");

        decimalA = decimalA.add(decimalB);
        System.out.println("decimalA = " + decimalA);

        decimalA = decimalA.multiply(decimalB);
        System.out.println("decimalA = " + decimalA);

        decimalA = decimalA.subtract(decimalB);
        System.out.println("decimalA = " + decimalA);

        decimalA = decimalA.divide(decimalB);
        System.out.println("decimalA = " + decimalA);

        decimalA = decimalA.pow(2);
        System.out.println("decimalA = " + decimalA);

        decimalA = decimalA.negate();
        System.out.println("decimalA = " + decimalA);
    }
}

Our code snippet results are:

decimalA = 98765432123456799
decimalA = 987654321234567990
decimalA = 987654321234567980
decimalA = 98765432123456798
decimalA = 9754610582533151990855052972412804
decimalA = -9754610582533151990855052972412804
