2 класс математика вычисли значения выражений : (89+4) - 8, (38+7) - 9, (84+9) - 8, (65-8) + 5, (73-6) + 9, (64-7) + 5, (72-5) + 9, 8 + (44-7), 7 + (23-5), 8 + (45-8), 6 + (24-5.

(89+4) - 8=93-8=85

(38+7) - 9=45-9=36

(84+9) - 8=93-8=85

(65-8) + 5=57+5=62

(73-6) + 9=67+9=76

(64-7) + 5=57+5=62

(72-5) + 9=67+9=76

8 + (44-7) = 8+37=45

7 + (23-5) = 7+18=25

8 + (45-8) = 8+37=45

6 + (24-5) = 6+19=25
