The length of an iron rod is `(16.4+-0.1)cm`. If a small piece of length `(1.2+-0.1)cm` is cut out, what is the length of the remaining rod?

Explanation

To solve the problem step by step, we need to find the length of the remaining iron rod after cutting out a small piece, taking into account the uncertainties in the measurements.

### Step 1: Identify the lengths and their uncertainties
- Length of the iron rod (L1) = \(16.4 \, \text{cm} \pm 0.1 \, \text{cm}\)
- Length of the piece cut out (L2) = \(1.2 \, \text{cm} \pm 0.1 \, \text{cm}\)

### Step 2: Calculate the length of the remaining rod
To find the length of the remaining rod (L_remaining), we subtract the length of the cut piece from the original length of the rod:
