Números inteiros opostos ou simétricos vamos considerar os pontos a e b na reta

Integer opposite or symmetrical
we will consider the points a and b on the line
_____A_4 Unidades____________4 unidades____________b_____
-4 -3 -2 -1 0 +1 +2 +3 +4
The points a and b are symmetric or opposite because they are the same distance
ie +4 and -4 are integers opposite or symmetrical
opposite 8 -: - (-8) = 8
opposite +5 = -5
and zero and symmetric himself
