bonjour
le programme il suffit se suivre les instructions
2
2 - 3 = - 1
- 1 * - 5 = 5
5 : 4 = 5/4
5/4 + 2 = 5/4 + 4/4 = 9 /4
9 /4 = 2.25
tu fais pareil avec les autres
n
n - 3
- 5 ( n - 3) = - 5 n + 15
(- 5 n + 15 ) / 4
( - 5 n + 15 ) / 4 + n
= ( - 5 n + 15 + 4 n ) / 4
= ( - n + 15 ) / 4
A = 8/5 + 28/25
A = 36/25
B = 53/30 - ( 6/20 + 2 /20)
B = 53/30 - 8/20
B = 106/60 - 24/60
B = 82/60
B = 41 /30
C = ( 2/4 - 3/4) x 16/9
C = - 1 /4 * 16/9
C = - 16/36
C = - 4 /9
D = ( 35/30 + 24/30) x 3/2 x 5/13
= 59/30 x 15/26
= 885/ 780
= 59/ 52
