Answer 2

3.  1) A ( adevarat )

    2) A ( adevarat )

    3) F ( fals )

    4) A ( adevarat )

    5) F ( fals )

4. a) 865 + 5 = 870

   b) 865 × 5 = 4325

   c) 865 - 5 = 860

5.  2742 × 3 + 1774 = 8226 + 1774 = 10000

6. 490 = 70 × 7

   490 = 230 + 260

   490 = 500 - 10

   7200 = 72 × 100

  7200 = 6800 + 400

   7200 = 8000 - 800

   6000 = 60 × 100

   6000 = 5000 + 1000

   6000 = 8999 - 2999

7.  ( 98 × 89 + 1276 ) - 9998 =

    ( 8722 + 1276 ) - 9998 =

    9998 - 9998 =

   = 0
