expected primary-expression before '>' token

Hello i'm just learning arduino and couldn't find my mistake and dont really know what this error message wants to say.

ERROR MESSAGE :[bexit status 1
expected primary-expression before '>' token[/b]

void setup() {

Serial.begin(9600);
pinMode(13, OUTPUT);
}

void loop() {

int sensorValue = analogRead(A0);
if (sensorValue) > 90;
digitalWrite (13, 0);
else
digitalWrite(13, HIGH);
Serial.println(sensorValue);
delay(1);
}

Well you underlined the mistake, have you considered consulting the Arduino documentation on the IF statement?

  if (sensorValue) > 90;

Misplaced brace and erroneous semicolon
Should be

  if (sensorValue > 90)
