5 + 6 - (-3) - 8 + 4 -3
Komok [63]
Okay, so -

We have one very important thing here. This little part <em>6 - (-3). </em>

Now, it's essential to remember that when we have two negatives like this, we simply draw a line straight down. It becomes a positive! 

So, our question is essentially <em>5 + 6 + 3 - 8 + 4 - 3 = ?</em> instead of <em>5 + 6 - (-3) - 8 + 4 - 3!</em> =)

With that in mind, we simply solve left to right. 

<em>11 + 3 - 8 + 4 - 3 = ?</em>

<em>14 - 8  + 4 - 3 = ?</em>

<em>6 + 4 - 3 = ?</em>

<em>10 - 3 = ?</em>

<em>7</em> is our final answer! =)
