A Friedman number is an integer, which in a given base, is the result of an expression using all its own digits in combination with any of the four basic arithmetic operators (+, −, ×, ÷), additive inverses, parentheses, and exponentiation. For example, 347 is a Friedman number, since 347 = 73 + 4. The first few base 10 Friedman numbers are:
Friedman numbers are named after Erich Friedman, as of 2013 an Associate Professor of Mathematics and ex-chairman of the Mathematics and Computer Science Department at Stetson University, located in DeLand, Florida.
Results
Parentheses can be used in the expressions, but only to override the default operator precedence, for example, in 1024 = (4 − 2)10. Allowing parentheses without operators would result in trivial Friedman numbers such as 24 = (24). Leading zeros cannot be used, since that would also result in trivial Friedman numbers, such as 001729 = 1700 + 29.
A nice or "orderly" Friedman number is a Friedman number where the digits in the expression can be arranged to be in the same order as in the number itself. For example, we can arrange 127 = 27 − 1 as 127 = −1 + 27. The first nice Friedman numbers are:

Friedman Test [Simply Explained]
The Friedman test analyzes whether there are statistically significant differences between three or more dependent samples.
The Friedman test is the non-parametric counterpart of the analysis of variance with repeated measures.

A Friedman number is an integer, which in a given base, is the result of an expression using all its own digits in combination with any of the four basic arithmetic operators (+, −, ×, ÷), additive inverses, parentheses, and exponentiation. For example, 347 is a Friedman number, since 347 = 73 + 4. The first few base 10 Friedman numbers are:
Friedman numbers are named after Erich Friedman, as of 2013 an Associate Professor of Mathematics and ex-chairman of the Mathematics and Computer Science Department at Stetson University, located in DeLand, Florida.

Parentheses can be used in the expressions, but only to override the default operator precedence, for example, in 1024 = (4 − 2)10. Allowing parentheses without operators would result in trivial Friedman numbers such as 24 = (24). Leading zeros cannot be used, since that would also result in trivial Friedman numbers, such as 001729 = 1700 + 29.
A nice or "orderly" Friedman number is a Friedman number where the digits in the expression can be arranged to be in the same order as in the number itself. For example, we can arrange 127 = 27 − 1 as 127 = −1 + 27. The first nice Friedman numbers are:
