There is no formula to answer this question. All we need to do is, apply trial by error method to for each expression.
Possible expression and their results are:
[tex]- 1 + 2 * 3 - 4 = 1[/tex]
[tex]1 + 2 + 3 - 4 = 2[/tex]
[tex]0 * 3 + 1 + 2 = 3[/tex]
[tex]0 * 2 + 1 + 3 = 4[/tex]
[tex]1 * 3 + 4 - 2 =5[/tex]
[tex]0 + 1 + 2 + 3 = 6[/tex]
[tex]0 + 1 + 2 * 3 = 7[/tex]
[tex]3 + 4 - 5 + 6 = 8[/tex]
[tex]1 * 2 + 3 + 4 =9[/tex]
[tex]1 + 2 + 3 + 4 =10[/tex]
[tex]2^3 + 4 - 1 = 11[/tex]
[tex]5 + 6 - 7 + 8 =12[/tex]
[tex]4^2 - 3 * 1 = 13[/tex]
[tex]2 + 3 + 4 +5=14[/tex]
[tex]2 * 3 +4 + 5 = 15[/tex]
[tex]4 * (3 - 1)^2 = 16[/tex]
[tex]3 * 5 + 4/2 = 17[/tex]
[tex]3 + 4 + 5 + 6 = 18[/tex]
[tex]2 + 3 * 4 + 5 = 19[/tex]
[tex]3 + 2^4 + 1 = 20[/tex]
[tex]4 * 5 - 6 + 7 = 21[/tex]
[tex]4 + 5 + 6 + 7 =22[/tex]
[tex]3 * 4 + 5 + 6 = 23[/tex]
[tex]5^2 -4 + 3 = 24[/tex]
[tex]2^5 - 4 - 3 = 25[/tex]
[tex]5 + 6 + 7 +8 = 26[/tex]
[tex]\frac{3^4}{5-2} =27[/tex]
[tex]5 * 4 + 2^3 = 28[/tex]
[tex]3 + 4 * 5 + 6 = 29[/tex]
[tex]6 + 7 + 8 +9 = 30[/tex]
