Hello! The thing about factorials is that they are VERY BIG. 100! has 158 digits, and most calculators won't go higher than 100, which happens at 70! When handling combinations, you should become familiar with how to reduce factorials. For example, in your screenshot you have (100 3), which can also be written as 100 C 3, and the formula for those is: 100! / ((100-3)!*3!) = 100! / (97!* 3!) Think about how 100! breaks down: 100 * 99 * 98 * 97 * 96 * ... * 2 * 1. If you group together all of the terms after 97, you can change this to 100! = 100 * 99 * 98 * 97! Since you have 97! in the numerator and denominator, you can cancel those and rewrite the fraction: 100!/(97!*3!) = 100*99*98/3!, which can be plugged into a calculator to get 161700.

Another way is to express factorials in terms of some other base n! = 1 * 2 * 3 * 4 * ... * n n! = (e^ln(1)) * (e^ln(2)) * (e^ln(3)) * ... * (e^ln(n)) n! = e^(ln(1) + ln(2) + ln(3) + ... + ln(n)) n! = e^sigma(ln(t) , t = 1 , t = n) Surely your calculator can handle ln(1) + ln(2) + ... + ln(100) nCk => n! / (k! * (n - k)!) => e^sigma(ln(t) , t = 1 , t = n) / (e^sigma(ln(t) , t = 1 , t = k) * e^sigma(ln(t) , t = 1 , t = (n - k)) Looks like hell, I know, but your calculator can handle it. e^(sigma(ln(t) , t = 1 , t = n) - sigma(ln(t) , t = 1 , t = k) - sigma(ln(t) , t = 1 , t = n - k)) You don't need it to evaluate 100C97, but 100C50 gets pretty tedious to enter on a calculator. You can use Stirling's Approximation, too. n! is approximately sqrt(2 * pi * n) * (n/e)^n. 100! = 9.3326215443944152681699238856267 * 10^157 sqrt(2 * pi * 100) * (100/e)^100 = 9.3248476252693432477647561271787 * 10^157 9.3326 * 10^157 compared to 9.3248 * 10^157. Not a bad approximation. nCk => sqrt(2 * pi * n) * (n/e)^n / (sqrt(2 * pi * k) * (k/e)^k * sqrt(2 * pi * (n - k)) * ((n - k) / e)^(n - k)) => sqrt(2 * pi * n / (4 * pi^2 * k * (n - k))) * (n/e)^n * (e/k)^k * (e/(n - k))^(n - k) => sqrt(n / (2 * pi * k * (n - k))) * n^n * e^k * e^(n - k) / (e^n * k^k * (n - k)^(n - k)) => sqrt(n / (2pi * k * (n - k))) * n^n * e^(k + n - k - n) * k^(-k) * (n - k)^(k - n) => sqrt(n / (2pi * k * (n - k))) * n^n * 1 * k^(-k) * (n - k)^(k - n) => sqrt(n / (2pi * k * (n - k))) * n^n * k^(-k) * (n - k)^(k - n) 100C50 = 100,891,344,545,564,193,334,812,497,256 Approximation sqrt(100 / (2 * pi * 50 * 50)) * 100^100 * 50^(-50) * 50^(-50) sqrt(50 / (pi * 2500)) * 100^100 * 50^(-100) sqrt(1 / (50 * pi)) * (100/50)^100 sqrt(1 / (50 * pi)) * 2^100 101,143,884,241,458,946,587,585,663,181.38... Off by about 0.3%, which is good enough, if you think about it. And that's just at a small number like 100. It just gets better as n gets bigger.
