What does the assignment operator '=' do in PowerShell?

It assigns the value on the right side to the variable on the left side. For example, $x = 5 sets the variable $x to 5.

How does the '+=' operator work in PowerShell?

It adds the value on the right to the current value of the variable on the left and then assigns the result back to that variable. For example, $x += 3 means $x = $x + 3.

What is the difference between '=' and '-=' operators?

= assigns a new value to a variable. -= subtracts the right value from the variable's current value and assigns the result back. For example, $x -= 2 means $x = $x - 2.

Can you use '*=' operator in PowerShell? What does it do?

Yes, *= multiplies the variable's current value by the right value and assigns the result back. For example, $x *= 4 means $x = $x * 4.

Explain how the '/=' operator works with an example.

The /= operator divides the variable's current value by the right value and assigns the result back. For example, $x /= 2 means $x = $x / 2. It works with numbers.

What does the operator '+=' do in PowerShell?

A Adds the right value to the variable and updates it

B Assigns the right value to the variable without change

C Subtracts the right value from the variable

D Divides the variable by the right value

The '+=' operator adds the right value to the current variable value and assigns the result back.

Which operator assigns a new value to a variable?

A *=

B =

C -=

D /=

The '=' operator assigns a new value to a variable.

If $x = 10, what is the value of $x after $x -= 4?

A 6

B 14

C 4

D 40

The '-=' operator subtracts 4 from 10, so $x becomes 6.

What will $x *= 3 do if $x is 5?

A Set $x to 2

B Set $x to 8

C Set $x to 15

D Set $x to 53

The '*=' operator multiplies $x by 3, so 5 * 3 = 15.

Which operator divides the variable by a value and updates it?

A +=

B *=

C -=

D /=

The '/=' operator divides the variable by the right value and assigns the result back.

Describe how assignment operators like '=', '+=', and '-=' work in PowerShell with simple examples.

Think about how you update a variable's value step by step.

Explain why assignment operators are useful in scripting and how they help automate tasks.

Consider how you might keep track of counts or totals in a script.
