Question

subtract.
-1 - (-2) =
2 - (-4) =

Explanation:

Step1: Simplify \(-1 - (-2)\)

Recall the rule: subtracting a negative is adding the positive. So \(-1 - (-2) = -1 + 2\).
\(-1 + 2 = 1\).

Step2: Simplify \(2 - (-4)\)

Using the same rule, \(2 - (-4) = 2 + 4\).
\(2 + 4 = 6\).

Answer:

For \(-1 - (-2)\), the answer is \(1\); for \(2 - (-4)\), the answer is \(6\).
