Arrow from 0 to -8 (pointing left). Another arrow from -8 to -6 (pointing right)
See diagram below
================================================================
Explanation:
Let's think of this in terms of money. Writing -8 means we are 8 dollars in debt. Since -8 is listed first, this means we start at 0 and go 8 units to the left along the number line, to land on -8.
Then we'll go 2 units to the right to land ultimately at -6. This is because of the "-(-2)" portion, which is the same as "+2". Subtracting a negative is the same as adding. The two negatives cancel each other out.
Going back to the money example, if we have a balance of -8 (we're 8 dollars in debt) and taking away 2 IOU notes means we're 6 dollars in debt. Subtracting a negative can be thought of as taking away debt.
Side note: If we had -8-2, then we would go 2 units to the left of -8 to land on -10 instead.
53(1 + x)
the 53 is the cost of the meal without the tax
the x is gonna be the percentage of the tip u want to leave...in decimal form
so lets say u are going to leave a 5% tip.....5% = 0.05
ur equation would be 53(1 + 0.05) = 53(1.05) = 55.65...cost of meal and tip
