解題步驟

1. Understand the question

   which number line models $-1 + (-14)$? add. $-1 + (-14) = \\square$

2. Explanation

   Step1: Recall the rule for adding negative numbers

   When adding two negative numbers, we add their absolute values and keep the negative sign. So for \(-1 + (-14)\), we can think of it as \(-(1 + 14)\).

   Step2: Calculate the sum of the absolute values

   First, find the sum of \(1\) and \(14\). \(1+14 = 15\).

   Step3: Apply the negative sign

   Since both numbers are negative, the result is \(-15\).

3. Final answer

   \(-15\)
