Vreau cum se face toate punctele ​

a)a=|-2|-|-5|+|+8|-|-3+5|

a=2-5+8-|2|

a=2-5+8-2

a=-5+8

a=+(8-5)

a=3

b)b=|5-2³|-|5-2²|-|3²-1|+|13-4²|

b=|5-8|-|5-4|-|9-1|+|13-16|

b=|-3|-|1|-|8|+|-3|

b=3-1-8+3

b=6-1-8

b=6-9

b=-3

c)c=|-7|+|2³-3²|-|3³-5²|

c=7+|8-9|-|27-25|

c=7+|-1|-|2|

c=7+1-2

c=8-2

c=6

d)d=-8-|-12|+|-6²+5²|-|-7+2³|

d=-8-12+|-36+25|-|-7+8|

d=-8-12+|-11|-|1|

d=-8-12+11-1

d=-21+11

d=-(21-11)

d=-10
