when it's ! it means it's a factorial, so basically it's the number you have multiplied by all the numbers down to 1 so just count down to 1 from 9 9 * 8 * 7 * 6 * 5 * 4 * 3 *2 *1 multiply all those numbers together and you get your answer

ahhh so that BIG PI is multiplication and sigma is addition
