make 17 out of 1,3,3,6
Make 43 out of 2,5,7,8


U cant Make them Decimals or anythig u gotta use +/-/x/division

Answer 1

You don't say you can only use each number once, or that you must use all of them. 17 = 3•6-1, for example, leaving out the extra 3. 43 = 5•7+8, leaving out the 2. 34 = 7(6-2)+6, using 6 twice and leaving out 1.
