How To Add Fractions On A Graphing Calculator

hi, this is rob. i’m going to show you howto calculate factorials on the ti 84 plus ce graphing calculator. but first, what is a factorial. a factorialis when you take a number, let’s use the number 5, and we multiply that number 5 byall the numbers below it. for example, let’s calculate 5 factorial.first we write 5 factorial. this exclamation

How To Add Fractions On A Graphing Calculator, point is the symbol we use for factorial.5 factorial is equal to 5 times 4 times 3 times 2 times 1. which is equal to 120. now let’s see how to calculate factorialson the ti 84 plus ce calculator. we are going to calculate 5 factorial.

first enter the number 5. now we want to enterthe factorial symbol after the 5. to do that, press this math key here. thismenu will pop up. use the right arrow key and go to prob. prob stands for probability.and if you look down at number 4 you see that exclamation point.that is our factorial symbol.go down to number 4 and press enter. now the screen is showing 5 factorial. tocalculate 5 factorial, just press the enter key here. and the answer is to the right,120. let’s do a larger number, say 50 factorial.enter a 50. enter the factorial symbol by pressing the math key here. use the rightarrow key and go to prob for probability. go down to number 4. press the enter key.now we are showing 50 factorial. to calculate

50 factorial press the enter key. the answeris 3.04140932 to e 64. that e64 means 10 to the 64th power. thus you have to move thatdecimal point here, to the right 64 places. that will make this a very large number. thatis a very large number. in fact there is a limit in this calculatorin which you can calculate factorials. if you calculate a factorial of a number toolarge you will get an error message. for example, say we want to calculate 70 factorial. and we get the message, error, overflow. 70factorial is too large of a number for this calculator. so what is the largest numberwe can do a factorial using this method. for this calculator that number is 69.

and there is the answer to the right. 1.711224524times 10 to the power 98. ok, that is it, if you like this video, pleasegive it a thumbs up and please subscribe to this channel.
