Question

calcule as adições algébricas :

Answer 1

f) $(-52)-(-52)=-52+52=0$

g) $-2+(-1)-6=-2-1-6=-9$

h) $9-(-7)-11=9+7-11=16-11=5$

i) $15-(+9)-(-2)=15-9+2=17-9=8$

j) $10-2-5-(+2)-(-3)=10-2-5-2+3=13-9=4$

Answer 2

Resposta:

$f)(-52)-(-52)=0$

$g)-2+(-1)-6\\-2-1-6\\-3-6\\-9$

$h)9-(-7)-11\\9+7-11\\16-11\\5$

$i)15-(+9)-(-2)\\15-9+2\\6+2\\8$

$j)10-2-5-(+2)-(-3)\\10-2-5-2+3\\8-5-2+3\\3-2+3\\1+3\\4$

$k)-25-(-5)-30\\-25+5-30\\-20-30\\-50$

$l)-(+7)-4-12\\-(7+4+12)\\-(11+12)\\-23$

$m)5-(-5)+3-(-3)+0-6\\5+5+3+3-6\\10+3+3-6\\13+3-6\\16-6\\10$

$n)-10-7-6-(-15)-2-(-10)\\-10-7-6+15-2+10\\-17-6+15-2+10\\-23+15-2+10\\-8-2+10\\-10+10\\0$
