    6)
    (2.8)+7+2
    = 16+7+2
    =25

    7)
    3+ (5.2)-8
    =3+ 10 -8
    =5

    8)
    (6.2) +7 -8
    = 12 +7 -8
    =11

    9)
    10 -5 + (7.2)
    =10 -5 +14
    =19

    10)
    15 +2 - (2.6)
    =15 +2 -12
    =5
  • 6. 2 × 8 + 7 + 2
    = ( 2 × 8 ) + 7 + 2
    = 16 + 7 + 2
    = 23 + 2
    = 25

    7. 3 + 5 × 2 - 8
    = 3 + ( 5 × 2 ) - 8
    = 3 + 10 - 8
    = 13 - 8
    = 5

    8. 6 × 2 + 7 - 8
    = ( 6 × 2 ) + 7 - 8
    = 12 + 7 - 8
    = 19 - 8
    = 11

    9. 10 - 5 + 7 × 2
    = 10 - 5 + ( 7 × 2 )
    = 10 - 5 + 14
    = 5 + 14
    = 19

    10. 15 + 2 - 2 × 6
    = 15 + 2 - ( 2 × 6 )
    = 15 + 2 - 12
    = 17 - 12
    = 5
