Question

add.
$-2 + (-2) = square$
$-6 + 4 = square$

Explanation:

Step1: Calculate \(-2 + (-2)\)

When adding two negative numbers, we add their absolute values and keep the negative sign. The absolute value of \(-2\) is \(2\), so \(2 + 2 = 4\), and since both numbers are negative, the result is \(-4\). So \(-2 + (-2)= -4\).

Step2: Calculate \(-6 + 4\)

When adding a negative and a positive number, we subtract the smaller absolute value from the larger one and take the sign of the number with the larger absolute value. The absolute value of \(-6\) is \(6\) and of \(4\) is \(4\). \(6 - 4 = 2\), and since \(-6\) has the larger absolute value, the result is \(-2\). So \(-6 + 4 = -2\).

Answer:

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