(0,95-1,82):1,7=3,4

I’ll interpret using decimal commas as in many European formats: (0,95 − 1,82) : 1,7 = 3,4.

• Compute: 0,95 − 1,82 = −0,87
• Then (−0,87) : 1,7 means −0,87 / 1,7 = −87/170 ≈ −0,5118

So the left side is about −0,5118, not 3,4. The statement “= 3,4” is false as written.

If you meant something else (e.g., a missing value, or different parentheses, or using decimal dots), share the exact problem text and I’ll solve it.
