GoodCalc is a programming language that allows you to perform many calculations very easily and efficiently. The syntax is as follows:

/function arg1 arg2

So, they are prefix functions. Right now, GoodCalc is in Version 3.0, and as of now, the overall time to calculate operations has been reduced by 40%. GoodCalc is pretty easy to use, and I'm just gonna highlight some of my favorite functions.

>>> /pascr 16 #Sixteenth row of Pascal's Triangle 1 16 120 560 1820 4368 8008 11440 12870 11440 8008 4368 1820 560 120 16 1

>>> /primerange 3 300 #Primes from [3,300) 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101 103 107 109 113 127 131 137 139 149 151 157 163 167 173 179 181 191 193 197 199 211 223 227 229 233 239 241 251 257 263 269 271 277 281 283 293

There are a bunch of other cool one like /randcho a list_1 list_2 ... list_n, it chooses a random item form the list. Overall, it's a very fast, easy to use mathematical language.
