Page 13 - E-Modul Operasi Bilangan Bulatl

Contoh Soal
1. 4 + 3 =

2. 6 – 4 =

3. -3 – (-2) =
4. 9 – (-5) =

Penjumlahan dan Pengurangan Bilangan Bulat Berlaku :
1. a + b = a + b

2. a – b = a + (-b )
3. -a + (-b) = – (a + b)

4. a – (-b) = a + b

Penyelesaian
1. 4 + 3 = 7

2. 6 – 4 = 6 + (-4) = 2

3. -3 – (-2) = – (3+2) = -1

4. 9 – (-5) = 9 + 5 = 14
