### Today we will add with negative integers.

integers=numbers that consist of whole numbers and their opposites

Concept

• When you get older and you start to “collect” credit cards and you start to buy things on “credit” you will be borrowing from the banks.

• You buy an iPod for \$199.00

• You now owe \$199.00 (-199)

• You buy a laptop for \$599.00

• You now owe \$599.00 (-599)

• All together you owe \$798.00

• (-798)

Add cards and you start to buy things on “credit” you will be borrowing from the banks.

• Add means to put together.

\$199.00 + \$299.00=\$498.00

\$300.00 + \$600.00=\$900.00

Absolute Value cards and you start to buy things on “credit” you will be borrowing from the banks.

The absolute value of an integer is its distance from zero on the number line.For example, |-3| = 3 and |-5| = 5.

Importance cards and you start to buy things on “credit” you will be borrowing from the banks.

• It will help you be a good “borrower” since you know how much you owe and how much you will have in order to pay.

• It will be on tests and you need to know how to do it!

• What would be other reasons to know how to add integers?

1.  Find the absolute value of each integer.

2. Subtract the smaller number from the larger number you get in Step 1.

3. The result from Step 2 takes the sign of the integer with the greater absolute value.
