Your're given 4 single digit numbers... You can only apply 4 operations on them: addition/subtraction/multiplication/division... You can use as many brackets as you like... All digits must be used once and only once... You cannot combined digits together to form larger numbers (e.g. 1 and 2 must be treated separately and not as 12 or 21 together)... Nor could you express any decimal number using "."...

Examples:

- Code: Select all
`1,2,3,4: 24=1*2*3*4`

5,6,7,8: 24=(7+5)*(8-6)

0,3,6,8: 24=8*3+(6*0)

1,9,8,6: 24=1*(9-6)*8

Could anyone work out how to do this for:

1,3,4,6
