Assignment Operators
Assignment operators are used in programming to assign a value to a variable. They are used to modify the value of a variable by performing an operation on the current value and a new value, and then assigning the result back to the variable.
Types of Assignment Operators
There are several types of assignment operators commonly used in programming:
- Simple Assignment Operator (=): Assigns the value on the right side to the variable on the left side.
- Addition Assignment Operator (+=): Adds the value on the right side to the current value of the variable and assigns the result back to the variable.
- Subtraction Assignment Operator (-=): Subtracts the value on the right side from the current value of the variable and assigns the result back to the variable.
- Multiplication Assignment Operator (*=): Multiplies the value on the right side with the current value of the variable and assigns the result back to the variable.
- Division Assignment Operator (/=): Divides the current value of the variable by the value on the right side and assigns the result back to the variable.
Examples
Here are some examples of how assignment operators are used in programming:
Simple Assignment Operator
```javascript var x = 10; // x is assigned the value 10 ```Addition Assignment Operator
```javascript var y = 5; y += 3; // y is assigned the value of y + 3, which is 8 ```Subtraction Assignment Operator
```javascript var z = 12; z -= 4; // z is assigned the value of z - 4, which is 8 ```Multiplication Assignment Operator
```javascript var a = 2; a *= 5; // a is assigned the value of a * 5, which is 10 ```Division Assignment Operator
```javascript var b = 20; b /= 4; // b is assigned the value of b / 4, which is 5 ```Study Guide
To master the concept of assignment operators, here are a few study tips:
- Understand the syntax and usage of each assignment operator.
- Practice using assignment operators in different programming languages such as JavaScript, Python, or Java.
- Work on coding exercises that involve the use of assignment operators to modify variable values.
- Experiment with complex expressions involving assignment operators to deepen your understanding.
By mastering assignment operators, you will gain a strong foundation in programming and be able to manipulate variable values effectively.

Probability: Students understand that when all outcomes of an experiment are equally likely, the theoretical probability of an event is the fraction of outcomes in which the event occurs. Students use theoretical probability and proportions to make approximate predictions.
