You need to use precedence. It should look like this.
6+(4×5) -1 +(3÷4)

{6[(+4 x 5) - (1 + 3)]} / 4
{6 [(20) - (4) ] }/ 4
{6 [ 16 ]} /4
96/4
24
I used the +4 to indicate the sign of the result, rather then addition
I started by looking at the / 4 at the end, which meant the rest of the equation had to be = 96, I lucked out in that I started with 96 as there were other combinations to look at as well

6 + 4 x 5 - 1 + 3 ÷ 4 =
6 + 20 - 1 + 3 ÷ 4=
6 + 20 - 1 + 0.75 =
26 - 1 + 0.75 =
25 + 0.75
25.75
The answer is 25.75

You have to put it like this
6+(4*5)-1+(3\4)
then it will become
26-7/4
its value 24.25

In a quick look, I'm stumped. The nearest I'm getting is 25. Are you sure there isn't a typo?
