Question

a) 15 - { - 32 + [+ 10 - 8 - ( -5 + 3 ) ] } =

b) 10 - 8 + { - 25 + 4 - [ - 10 + 16 - 3 + ( + 6 - 4 ) ] } =

c) { - 13 + 7 - [ - 8 + 5 - 10 + 2 - ( + 6 - 4 ) + 4 - ( 10 - 9 ) + 2 }​

Answer 1

a) 15-{-32+[+10-8-(-5+3)]}=

15-{-32+[+10-8-2]}=

15-{-32+0}=

15-{-32}=

=47

b) 10-8+{-25+4-[-10+16-3+(+6-4)]}=

10-8+{-25+4-[-10+16-3+2]}=

10-8+{-25+4-5}=

10-8+(-26)=

=-24
