Question

add.
$2 + (-4) = \square$
$-3 + (-4) = \square$

Explanation:

Step1: Calculate \(2 + (-4)\)

Using the rule of adding a negative number (which is equivalent to subtracting the positive of that number), we have \(2+(-4)=2 - 4\). Since \(4-2 = 2\) and \(4>2\), the result is \(-2\).

Step2: Calculate \(-3+(-4)\)

Adding two negative numbers: we add their absolute values and keep the negative sign. So, \(\vert - 3\vert+\vert - 4\vert=3 + 4 = 7\), and since both numbers are negative, the result is \(-7\).

Answer:

For \(2+(-4)\), the answer is \(-2\).
For \(-3+(-4)\), the answer is \(-7\).
