Penjumlahan-operasi hitung
Sifat - sifat dari penjumlahan :
a + b = b + a
(-a) + (-b) = -(a + b)
a + (-b) = (-b) + a = -(b - a)
Contoh :
3 + 8 = 8 + 3 = 11
(-5) + (-2) = -(5 + 2) = -7
7 + (-8) = (-8) + 7 = -(8 - 7) = -1

Pengurangan-operasi hitung
Sifat - sifat dari pengurangan :
a - b = a + (-b)
(-a) - (-b) = (-a) + b= -(a - b)
a - (-b) = a + b
(-a) - b = -(a + b)
Contoh :
4 - 1 = 4 + (-1) = 3
(-5) - (-1) = (-5) + 1= -(5 - 1) = -4
4 - (-3) = 4 + 3 = 7
(-2) - 6 = -(2 + 6) = -8
