**EDIT: Thanks a ton for everyone who has helped. I can't believe I missed that single typo.**

I'm in need of help for some basic math in Java. I'm trying to create a heat index calculator but when Java compiles runs the program the calculator seems to slip up. I've checked it over multiple times to see the problem but cant find anything. Help would be greatly appreciated.

Code:

`double t = 84.3; //temperature`

int h = 81; //humidity

//the following are parts of the heat index formula

double c1 = -42.379;

double c2 = 2.04901523;

double c3 = 10.14333127;

double c4 = -0.22475541;

double c5 = -.00683783;

double c6 = -5.481717E-2;

double c7 = 1.22874E-3;

double c8 = 8.5282E-4;

double c9 = -1.99E-6;

double hI = c1 + c2 * t + c3 * h + c4 * t * h + c5 * t*t + c6 * h*h + c7 * t*t * h + c8 * t + h*h + c9 * t*t * h*h; //formula for calculating heat index

System.out.println(hI);

So the problem here is that instead of giving me the desired output (heat index), it's returning a very large number (6184.5981258548). Is there an issue with my code? Once again, any help would be appreciated. Thanks.

According to the Heat Index Wikipedia page, then `c8`

term should be:

c

_{8}TR^{2}

But you have for that term:

```
c8 * t + h*h
```

Try

```
c8 * t * h*h
```

Making this change, I get as output:

```
95.21440841480018
```

You have a typo in `c8*t + h*h`

It should be `c8*t*h*h`
