28. Найдем значения каждого выражения:
- $$23 + 25 \cdot 2 = 23 + 50 = 73$$
- $$54 - 13 \cdot 2 = 54 - 26 = 28$$
- $$4 \cdot 11 + 38 = 44 + 38 = 82$$
- $$14 \cdot 5 \cdot 0 = 70 \cdot 0 = 0$$
- $$22 \cdot (80 : 20) = 22 \cdot 4 = 88$$
- $$56 : 7 - 11 - 69 = 8 - 11 - 69 = -3 - 69 = -72$$
- $$3 : 3 \cdot 10 + 49 = 1 \cdot 10 + 49 = 10 + 49 = 59$$
- $$6 : 6 \cdot 40 = 1 \cdot 40 = 40$$
