### 1) $$ 18 \div (3 	imes 3) + 8 $$

**Steps:**
1. Calculate inside the parentheses: $$3 	imes 3 = 9$$.
2. Divide: $$18 \div 9 = 2$$.
3. Add: $$2 + 8 = 10$$.

**Answer:** $$10$$

---

### 2) $$ (100 - 8) - 4 + 6 $$

**Steps:**
1. Subtract inside the parentheses: $$100 - 8 = 92$$.
2. Subtract: $$92 - 4 = 88$$.
3. Add: $$88 + 6 = 94$$.

**Answer:** $$94$$

### 3) $$ 25 \div 5 + 12 \div 2 $$

**Steps:**
1. Divide: $$25 \div 5 = 5$$.
2. Divide: $$12 \div 2 = 6$$.
3. Add: $$5 + 6 = 11$$.

**Answer:** $$11$$

---

### 4) $$ 50 + (4 	imes 12) - 20 $$

**Steps:**
1. Multiply inside the parentheses: $$4 	imes 12 = 48$$.
2. Add: $$50 + 48 = 98$$.
3. Subtract: $$98 - 20 = 78$$.

**Answer:** $$78$$

---

### 5) $$ 80 \div (12 - 4) + 17 $$

**Steps:**
1. Subtract inside the parentheses: $$12 - 4 = 8$$.
2. Divide: $$80 \div 8 = 10$$.
3. Add: $$10 + 17 = 27$$.

**Answer:** $$27$$
