(-2,7-3:10³) *(-1) =
= ( -2,7 - 3 : 1000) * (-1) =
= (- 27/10 - 3 * 1/1000) * (-1) =
= (-27/10 - 3/1000) * (-1) =
= (-2700/1000 - 3/1000) * (-1) =
= -2703/1000 * (-1) =
= 2703/1000
-10 * (1 i 1/5 -5,5) =
= 10 * (6/5 - 55/10) =
= 10 * (12/10 - 55/10) =
= 10 * (-43/10)
= -43
-7razy(-10 do potęgi 2)-(-7) =
= -7 * (-100) + 7
= 700 + 7 =
= 707
