3 4. +4 - 5

I’m not sure how to read the layout. Could you confirm what you mean? Here are two plausible interpretations:

• If it’s a simple left-to-right expression: 34 + 4 - 5 = 33
• If you meant 3/4 + 4 - 5: then 0.75 + 4 - 5 = -0.25

If instead this is a long-division layout (with 5 as the divisor), please paste it again in a clearer form (e.g., using / or a simple ASCII layout), and I’ll solve it step by step.
