Error Messages on Arduino Starter Kit Project 3

I just finished writing the code for the 3rd project in the Arduino starter kit and I received Error messages that Im unable to understand( messages below the code): Please Help!

const int sensorPin = A0;
const float baselineTemp = 20.0;

void setup(){
Serial.begin(9600);

for( int pinNumber = 2;
pinNumber ++)
{ pinMode(pinNumber, OUTPUT);
digitalWrite( pinNumber, LOW);}
}

void loop(){
int sensorVal = analogRead(sensorPin);

Serial.print(“Sensor value:”);
Serial.print(sensorVal);

float voltage = (sensorVal/1024.0) * 5.0

Serial.print(", Volts:");
Serial.print(voltage);

Serial.print(", degrees C:");
float temperatire = (voltage - .5) * 100;
Serial.println(temperature);

if(temperature < baselineTemp) {
digitalWrite(2, LOW);
digitalWrite(3, LOW);
digitalWrite(4, LOW);

} else if(temperature >= baselineTemp+2 && temperature < baseline+4){
digitalWrite(2, HIGH);
digitalWrite(3, LOW);
digitalWrite(4, LOW);

} else if(temperature >= baselineTemp+4 && temperature < baselineTemp+6){
digitalWrite(2, HIGH);
digitalWrite(3, HIGH);
digitalWrite(4, LOW);

} else if(temperature >= baselineTemp+6){
digitalWrite(2, HIGH);
digitalWrite(3, HIGH);
digitalWrite(4, HIGH);

}

delay(1);

}


Arduino: 1.7.8 (Mac OS X), Board: “Arduino Uno”

Love-O-Meter.ino: In function ‘void setup()’:

for( int pinNumber = 2;
         pinNumber ++)

Take another look in the source code at that for loop.
It's missing an expression.

 float temperatire = (voltage - .5) * 100;

Spelling is important.

temperature < baseline+4){

baseline?

 float voltage = (sensorVal/1024.0) * 5.0

Missing semicolon.

Thank you so much!
