Question

subtract: -1 - 2 = \square

Explanation:

Step1: Recall subtraction of integers

Subtracting a positive number from a negative number is equivalent to adding the absolute values and keeping the negative sign. So, \(-1 - 2\) can be rewritten as \(-1 + (-2)\).

Step2: Add the absolute values

The absolute value of \(-1\) is \(1\) and the absolute value of \(-2\) is \(2\). Adding these absolute values gives \(1 + 2 = 3\). Since both numbers are negative, the result is negative. So, \(-1 - 2=-3\).

Answer:

\(-3\)
