Bonjour
= 32 + 4 + 5 + 2( − 1)
= 41 - 2
= 39
= 4(2 − 5) + 3( − 1)
= 4 x (-3) - 3
= (-12) - 3
= (-15)
= (2 − 3) − 2(32 − 5)
= (-1) - 2 x 27
= - 1 - 54
= (-55)
= (3 + 1)(2 + 3)
= 4 x 5
= 20
= (2 − 1)( − 3)
= 1 x (-3)
= (-3)
= (3 − 1)(2 − 3) + ( + 2)(3 − 5)
= 2 x (-1) + 2 x (-2)
= (-2) + (-4)
= (-6)
= (2 − 1)(2 + 3) − (3 − 4)( − 5)
= 1 x 5 - (-1) x (-5)
= 5 - 5
= 0
