Answer 1

Răspuns:

6+96+1 x(6+36):12

=102+1(6+36)/12

=102+ 42/12

=102+7/2

=204/2+7/2

=204+7/2

=211/2 ( 105 1/2 =105.5)

900-2 x[8 x (80-2400/12 x 50)]:4

=900-2 x[8 x (80-2400/600)]:4

=900-2 x [8 x (80 - 4):4

=900-2 x (8 x 76):4

=900 - 2 x 608/4

=900-2 x 152

=900-304

=596

( 112+288)  ( 100 x 50/10 x (1000/2)

=400 x ( 5000/10 x 50)

=400 x 5000/500

=400  x 10

=4000

=[(90-9):9+99]:2+77:7=

= [( 81/9+99]:2+77:7

=( 9+99):2 +11

=108/2 + 11

=54+11

= 65
