Today we will add with negative integers. Add=to put together
integers=numbers that consist of whole numbers and their opposites
Concept
Slide 2
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) APK
Slide 3
Add Add means to put together. $199.00 + $299.00=$498.00
$300.00 + $600.00=$900.00 Concept
Slide 4
Integer numbers that consist of whole numbers and their
opposites +500-500 +5-5 5 500 Concept
Slide 5
Absolute Value The absolute value of an integer is its distance
from zero on the number line. For example, | - 3| = 3 and | - 5| =
5.
Slide 6
Importance 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? IMP

Slide 8
What does this look like on a number line? + 9 + -8 SD
Slide 9
Lets try one! SD George owes his friend Jeanne $3. If he
borrows another $6, how much will he owe her altogether? -3 + -6
-9
Slide 10
SD +2 + - 7 -5
Slide 11
SD +5 + - 7 -2 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.
Slide 12
SD +9 + - 5 +4 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.
Slide 13
GP -12 + + 5 12 & 5 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. 12 5 7 -7
Slide 14
GP -15 + + 15 15 & 15 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. 15 15 0 0
Slide 15
GP +11 + -13 11 & 13 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. 13 11 2 -2
Slide 16
Lets review! What does add mean? To put together. What is an
integer? numbers that consist of whole numbers and their opposites.
What is the absolute value of -15? Of -6? Concept
