4つの4
149 = ( 4 / .4 ) 4 ! + 4 ! {\displaystyle 149={\sqrt {\sqrt {\sqrt {{({\sqrt {4}}/.4)}^{4!}}}}}+4!}
0 = 44 − 44
1 = 44 ÷ 44
2 = 4 ÷ 4 + 4 ÷ 4
3 = (4 + 4 + 4) ÷ 4
4 = 4 + (4 − 4) × 4
5 = (4 × 4 + 4) ÷ 4
6 = 4 + (4 + 4) ÷ 4
7 = 44 ÷ 4 − 4
8 = 4 + 4 + 4 − 4 = 4 × 4 − 4 − 4
9 = 4 + 4 + 4 ÷ 4
10 = (44 − 4) ÷ 4
