## Example: ``AND`` operator
This example turns on LED `3 , 3`, if LEDs `1 , 1` and `2 , 2` are both on:
```blocks
if (led.point(1,1) && led.point(2,2)) {
led.plot(3,3)
}
```
## Example: Comparisons of numbers and strings
When you compare two Numbers, you get a Boolean value, such as the comparison `x < 5` in the code below:
```blocks
input.onButtonPressed(Button.A, () => {
let x = Math.randomInt(5)
if(x < 5) {
basic.showString("low");
} else {
basic.showString("high");
}
})
```
See the documentation on [Numbers](/types/number) for more information on comparing two Numbers.
