4 4 23 quiz
Using the digits 4 4 2 and 3 in that order can we make all the whole numbers from 1 to 24?
We're looking for the simplest expression using only these digits and common mathematical symbols.
Acceptable symbols: + - × ÷ ( )
For example: 15 = 4×4+2-3, 21 = 44-23
1 = 4-4-2+3
2 = 4÷4-2+3
3 = 4+4-2-3
4 = -4÷4+2+3
5 = 4-4+2+3
6 = 4-4+2×3
7 = 4+4+2-3
8 = 4×(4+2)÷3
|
9 = 4+4-2+3
10 = 4×4−2×3
11 = 4×4-2-3
12 = (4+4)÷2×3
13 = 4+4+2+3
14 = 4+4+2×3
15 = 4×4+2-3
16 = 4+4+2³
|
17 = 4×4-2+3
18 = 4+42÷3
19 = 44÷2-3
20 = -4+4×2×3
21 = 44-23
22 = 4×4+2×3
23 = 4-4+23
24 = 4÷4+23

Just one expression each, thanks.
(they're all do-able)
