Identify the numerical coefficients of terms (other than constants) in the following expressions :
(i) `5-3t^2` (ii) `1+t+t^2+t^3` (iii) `x+2xy+3y` (iv) `100m + 100n`

Explanation

To identify the numerical coefficients of terms (other than constants) in the given expressions, we will analyze each expression step by step.

### Step 1: Analyze the first expression `5 - 3t^2`
- The constant term here is `5`.
- The term other than the constant is `-3t^2`.
- The numerical coefficient of `-3t^2` is `-3`.

### Step 2: Analyze the second expression `1 + t + t^2 + t^3`
