9. 4*8 24-12 16:2 9:3 32-16 5+4 18+3 21:3 3*8 12:4 15:3 7+8

Выполним вычисления:

$$4 \cdot 8 = 32$$

$$24 - 12 = 12$$

$$16 : 2 = 8$$

$$9 : 3 = 3$$

$$32 - 16 = 16$$

$$5 + 4 = 9$$

$$18 + 3 = 21$$

$$21 : 3 = 7$$

$$3 \cdot 8 = 24$$

$$12 : 4 = 3$$

$$15 : 3 = 5$$

$$7 + 8 = 15$$

Ответ: 32, 12, 8, 3, 16, 9, 21, 7, 24, 3, 5, 15
