Question

resuelve las siguientes operaciones​

Answer 1

Respuesta:

a) -12+26-8+15+23-20-25+10

=14-8+15+23-20-25+10

=6+15+23-20-25+10

=21+23-20-25+10

=44-20-25+10

=24-25+10

= -1+10

=9

b)-5+(-6)-(-5)+(-9)-(+7)+(-10)+7-12

= -5-6-(-5)+(-9)-(7)+(-10)+7-12

= -11+5-9-(7)+(-10)+7-12

= -6-9-(7)+(-10)+7-12

= -15-(7)+(-10)+7-12

= -22+(-10)+7-12

= -22-10+7-12

= -32+7-12

= -25-12

= -37

c) [-6+(4+2)-(-9)] - [(-4)-(+7-5)-(-12)]+7-15

= -27-[(-4)-(7-5)-(-12)]+7-15

= -27-6+7-15

= -41

d) 4+ {[-7+[3+2] -(-2)]+[(-3)-(+8-8)+(-10)]}+10-3

=4+0+[(-3)-(8-8)+(-10)]+10-3

=4+0-13+10-3

= -2
