buatlah garis bilangan 1. 10-7= 2. 6-(-2)= 3. -11-2= garis bilanganny yg jelas y

1.
.........3
....|---------->
...................................(-7)
.....................<---------------------------|
..........................10
.....|--------------------------------------->|
<--•---•---•---•---•---•---•---•---•---•---•---•-->
....0....1....2...3...4...5..6...7....8...9...10..11

10 - 7 = 3

2.

......................8

.................6
......|----------------------->
<---•---•---•---•---•---•---•---•---•---•---•-->
.....0....1....2...3...4...5...6...7...8...9...10

6 - (-2) = 6 + 2 = 8

3.
.....................(-13)

•---•---•---•---•---•---•---•---•---•---•---•---•---• -13-12-11-10.-9..-8.-7..-6..-5..-4.-3..-.2..-.1..0

-11 - 2 = -13
