In this video we start learning about at arithmetic operators, +, -, * and /.
Here is the source code contained in this video:
public class Main { public static void main(String[] args) { // declare variables int firstNum, secondNum, thirdNum, result; // assign some values to the variables firstNum = 7; secondNum = 14; thirdNum = 21; // perform some maths
// add-up result = (firstNum + secondNum); System.out.println("The result of the addition is " + result);
// subtract result = 0; result = (secondNum - firstNum); System.out.println("The result of the subtraction is " + result);
// multiply result = 0; result = (firstNum * secondNum * thirdNum); System.out.println("The result of the multiplication is " + result);
// divide result = 0; result = (thirdNum / firstNum); System.out.println("The result of the divide is " + result); } }
Here are the study notes from this video:
//Arithmetic operators are used to perform mathematical operations on the values contained in variables. //The + operator is used to add together two values. //The - operator is used to subtract one value from another. //The * operator is used to multiply two or more values. //The / operator is used to divide one value by another.
