4-3 +3 -1= 4 6

result: 3 Compute: 4 - 3 = 1; 1 + 3 = 4; 4 - 1 = 3. About the trailing “4 6”: could you clarify what you mean? Do you want the result to be 46, or are those digits for something else (a layout puzzle, or separate numbers to use later)? If you share a bit more context, I can tailor the answer.
