Question

Using exactly four 4's and any operation or symbols [+, -, *, /, (), x to the power of __], write an expression to equal each of the following:

1 = ________________ 4 = _______________ 7 = ________________
2 = ________________ 5 = _______________ 8 = ________________
3 = ________________ 6 = _______________ 9 = ________________

Answer 1

1→ (4/4) / (4/4) = 1/1 = 1

2→ (4*4) / (4+4)= 16/8 = 2

3→ (4+4+4)/4 = 12/4 = 3

4→ (4-4)*4 + 4= 0*4 + 4= 4

5→ (4*4 +4) /4 = 20/4 =5

6→ 4+(4+4)/4 = 4+ 8/4 = 4+2 =6

7→ 4+4 -4/4 = 8-1=7

8→ 4+4+4-4=12-4=8

9→ 4+4 + (4/4)= 8+1 =9
