Question

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

Explanation:

Step1: Calculate -2 + 4

To add a negative number and a positive number, we subtract the absolute values and take the sign of the number with the larger absolute value. The absolute value of -2 is 2, and the absolute value of 4 is 4. Since 4 > 2, we subtract 2 from 4: \(4 - 2 = 2\). So, \(-2 + 4 = 2\).

Step2: Calculate -4 + (-4)

To add two negative numbers, we add their absolute values and keep the negative sign. The absolute value of -4 is 4, so we add 4 and 4: \(4 + 4 = 8\), and then we keep the negative sign, so \(-4 + (-4) = -8\).

Answer:

For \(-2 + 4\), the answer is \(2\). For \(-4 + (-4)\), the answer is \(-8\).
