Must be a cheap way of getting an odd number.
Surely you can't use decimals - 0.4 uses a zero

Are we allowed factorials? Surely that "uses" a 3, 2 and 1 in the same way that a cube sign "uses" a 3

4! = 4 x 3 x 2 x 1 = 24
5! = 5 x 4 x 3 x 2 x 1 = 120
You multiply the number by every number before it.

It's a factoral.
n! means the product 1 × 2 × ... × n. so for 4 would mean 1 x 2 x 3 x 4.

Do you HAVE to use all four or can you use fewer i.e.
11 = 4!+(4/4)

Not lying. It was a typo. It IS factorial.

Yes factorial a are allowed
No .4 is still 0.4 however 4.4 uses two of the four 4's

2+3=5 (sub 2 & 3 taken from above)
That's seven 4s. You can only use four 4s.
