bonjour
on veut transformer ces soustractions en additions
quand on change le signe de soustraction " - " en signe d'addition " + "
il faut changer le signe du nombre qui suit
(+6) - (+3) =
(+6) + (- 3) = [ (+3) devient (-3) ]
(+3)
(+5) - (-4) =
(+5) + (+4) =
(+9)
(-7) - (+2) =
(-7) + (-2) =
(-9)
(-9) - (-8) =
(-9) + (+8) =
(-1)
(+6) - (+13) =
(+6) + (-13) =
(-7)
-------------
les 2 derniers
(+17) - 0 = 0 - (+15) =
(+17) + 0 = 0 + (-15) =
(+17) (-15)
