1-37+2.51 divided by 13

To answer this question, let's break it down step by step:

Step 1: Subtract 37 from 1.
1 - 37 = -36

Step 2: Add the result to 2.51.
-36 + 2.51 = -33.49

Step 3: Divide the result by 13.
-33.49 / 13 ≈ -2.576

Therefore, the final answer is approximately -2.576.

As written, that is

1 - 37 + 2.51/13
= 1 - 37 + 0.193
= -36 + 0.193
= -35.807

Use some parentheses if you want to evaluate that in some other way.
