Answer 1

6. 75.987=21204+11000+a
75987=53408+a
a= 75987-53408
a=22579

Answer 2

Explicație pas cu pas:

5. scaderea:

a-23.164= 12.521

a=12.521+23.164

a=45.685

adunarea:

111.231+b=999.777

b=999.777-111.231

a=888.546

scădere :

78.654-c=5322

c=5322+78.654

c= 131 .876

la 6 nu stiu imi pare rău

1. 1+3=4 2+1=3 2+3=5 4+3+5=12

1+3=4 2+1=3 7+1=8 4+3+8=15

1+2=3 4+1=5 3+1=4 3+5+4=12

2+3=5 2+4=6 4+3=7 5+6+7=18

1+2=3 2+4=6 4+1=5 3+6+5=14

2. a) x-280+213+319-109=1000

= 493+319

=1092-109

=907

=1000-907

=803

a=803

b) y+1200-580=2011

y=2011+1200=3211

y=3211-580=2610

y=2610
