Réduire une somme

Exemples : 5x + 3x = 8x x + x = 2x 10y - 7y = 3y

ExpressionLItterale

On supprime le signe x devant une lettre

On supprime le signe devant des parenthèses

Calculer en remplaçant la lettre par sa valeur numérique

Exemples : 6 x y = 6y a x a = a² 5 x c x 2 x c = 10c²

Exemple : 6 x ( a + 4) = 6 (a + 4)

Exemple : Si y = 3 alors A = 4y -7 A = 4 x y - 7 A = 4 x 3 - 7 A = 12 - 7 A = 5

Tester une égalité

Exemple : L'égalité 3b - 4 = 5 + 2b est -elle vraie pour b = 2 ? Membre de gauche : 3 x b - 4 =3 x 2 -4= 6-4 = 2 Membre de droite : 5 + 2 x b = 5 + 2 x 2 =5+4 =9 Les deux expressions n'ont pas la même valeur, donc l'égalité est fausse pour b = 2.

Programme de calcul

  • Choisir un nombre x
  • Lui retrancher 5 x - 5
  • Multiplier par 4 le résultat 4(x-5)

A greattitle here

Visual content is a transversal, universal language, like music. We are capable of understanding images from millions of years ago, even from other cultures. We don't like to bore. We don't want to be repetitive. Communicating as always bores and doesn't engage. We do it differently. We sabotage boredom. We create what the brain likes to consume because it stimulates it.
