Bonjour à tous, j'ai besoin de votre aide pour un exercice de math sur les nombres relatifs. Effectue les calculs suivants :
(-6) + (-9) =
(-5) + (+18) =
(+1,5) + (-15) =
(-15) - (+17) =
(-3) - (-1,5) =
(+3,5) - (-9,5) =
4 - 19 =
-18 +13 =
-8 -3 =
-0,5 - 19,5 =
-1 - (-1,5) =
-0,3 - 0,7 =
Merci d'avance.
