Form expressions (in three problems) that are equivalent to 100.

For each of these three problems, you must use all of the three

digits and no other digits.

Also, you are allowed only these:

concatenation of digits

decimal point

addition, subtraction, division**, multiplication signs

(and/or use grouping symbols for products)

grouping symbols such as parentheses, brackets, and braces

factorial symbol, and possible nesting of these is permitted

square root symbol, and nesting of these is also permitted

exponentiation

floor and ceiling functions

Hi;

**In mathematics, you don't understand things. You just get used to them.Of course that result can be rigorously obtained, but who cares?Combinatorics is Algebra and Algebra is Combinatorics.**

anonimnystefy,

his solution does only use three 3s and no other digits.

That "100" is not part of it as a base; it is following the equals sign as

what his expression is equal to.

Let me know if that is what you were referring to, please.
