Question

Transforme as operações em notações simplificadas e calcule as diferenças

(-8)-(+5)=

(-26)-(+28)=

(-10)-(-20)=

(-4)-(-8)=

(+26)-(+10)=

(-5)-0=

Answer 1

a)
(-8) - (+ 5) = - 8 - 5 = - 13
**************************************

b)
(-26)-(+28)= - 26 - 28 = - 54
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨

c)
(-10)-(-20)= - 10 + 20 = + 10
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨

d)
(-4)-(-8)= - 4 + 8 = + 4
¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨

e)
(+26)-(+10)= 26 - 10 = + 16

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
f)
(-5)-0= = - 5 - 0 = - 5
