Answer 1

$7 \times 4 - (47 - 17 - 2) \div 4 + 2 \times 7 - 6 \\ 1)47 - 17 - 2 = 28 \\ 2)28 \div 4 = 7 \\ 3)7 \times 4 = 28 \\ 4)2 \times 7 = 14 \\ 5)28 - 28 = 0 \\ 6)0 + 14 = 14\\7)14-6=8$

Answer 2

To solve the expression following the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's solve the expression step by step:

Step 1: Solve inside the parentheses/brackets 7 × 4 - (47 - 17 - 2) ÷ 4 + 2 × 7 - 6

47 - 17 - 2 = 28 So, the expression becomes: 7 × 4 - 28 ÷ 4 + 2 × 7 - 6

Step 2: Solve Division (from left to right) 7 × 4 - 28 ÷ 4 + 2 × 7 - 6

28 ÷ 4 = 7 So, the expression becomes: 7 × 4 - 7 + 2 × 7 - 6

Step 3: Solve Multiplication (from left to right) 7 × 4 - 7 + 2 × 7 - 6

7 × 4 = 28 2 × 7 = 14 So, the expression becomes: 28 - 7 + 14 - 6

Step 4: Solve Addition and Subtraction (from left to right) 28 - 7 + 14 - 6

28 - 7 = 21 21 + 14 = 35 35 - 6 = 29

So, the final result is: 7 × 4 - (47 - 17 - 2) ÷ 4 + 2 × 7 - 6 = 29
