Hey there! :)
3 - (-2) = ??
Let's keep in mind that a negative times a negative is always a positive!
In addition, let's also remember that parenthesis mean multiplication - so that's how we know that we're multiplying!
So, since a negative times a negative equals a positive, then we know that this question is essentially just asking us what 3 + 2 is!
In case we aren't sure how to do this, let's look at our fingers! We start out with 3 fingers, and add 2 more fingers to it! So, 3 fingers to 2 fingers equals 5 fingers!
Therefore, our answer is 5.
3 -(-2) = 5

Answer:
Therefore
m∠ DAB is 105°
Step-by-step explanation:
Given:
ABCD is a parallelogram. The diagram is not drawn to scale.
m∠CDA = 75°,
To FInd
m∠DAB = ?
Solution:
ABCD is a parallelogram.
AB || CD .......{opposite sides of a parallelogram are parallel}
∴∠CDA+∠DAB = 180°{SUM of the interior angles between parallel are supplementary}
substituting the values we get
Therefore
m∠ DAB is 105°
