ADDITION OF INTEGERS
•add integers using three different
ways: colored counters, number line
or rules.
Give the value of the following.
10
14
9
7
31. |3| =
2. |-10| =
3. |-14| =
4. |9|=
5. |-7| =
ADDITION OF INTEGERS
1. Colored Counters
-+
3 + 4 =
= zero pair
= 7
3 + (-4) = = -1
ADDITION OF INTEGERS
Colored Counters -+
-6 + 4 =
= zero pair
= -2
-2 + (-3) = = -5
2. Number Line
0 1 2 3 4 5 6 7 8-8 -7 -6 -5 -4 -3 -2 -1
- starts with the origin
- 6 + 4 = -2
ADDITION OF INTEGERS
2. Number Line
0 1 2 3 4 5 6 7 8-8 -7 -6 -5 -4 -3 -2 -1
Example:
move 5 units to the left and 6 units to the right
- starts with the origin
- 5 + 6 = 1
ADDITION OF INTEGERS
3. Rule: SAME SIGN, add and keep
DIFFERENT SIGN, subtract.
KEEP the sign of bigger number
And it will be EXACT.
ADDITION OF INTEGERS
