Answer 2

To solve these expressions, let's perform the operations in the correct order of operations (PEMDAS/BODMAS):

1. 7000×4 + (29000 + 7000)÷9×3 = ?
2. 8000×(14÷2)÷(1000-999) = ?
3. 9000 - (35000÷7 + 4000)÷9 = ?
4. 7000×7 - (8100÷9 + 1) = ?

Let's solve each step by step:

1. 7000×4 + (29000 + 7000)÷9×3 Step 1: Perform addition inside the parentheses first. 29000 + 7000 = 36000 Step 2: Perform division inside the parentheses. 36000 ÷ 9 = 4000 Step 3: Perform multiplication and addition from left to right. 7000×4 + 4000×3 = 28000 + 12000 = 40000

2. 8000×(14÷2)÷(1000-999) Step 1: Perform division inside the parentheses first. 14 ÷ 2 = 7 1000 - 999 = 1 Step 2: Perform multiplication and division from left to right. 8000×7 ÷ 1 = 56000

3. 9000 - (35000÷7 + 4000)÷9 Step 1: Perform division inside the parentheses first. 35000 ÷ 7 = 5000 Step 2: Perform addition inside the parentheses. 5000 + 4000 = 9000 Step 3: Perform subtraction and division from left to right. 9000 - 9000 ÷ 9 = 9000 - 1000 = 8000

4. 7000×7 - (8100÷9 + 1) Step 1: Perform division inside the parentheses first. 8100 ÷ 9 = 900 Step 2: Perform addition inside the parentheses. 900 + 1 = 901 Step 3: Perform multiplication and subtraction from left to right. 7000×7 - 901 = 49000 - 901 = 48099

So, the expressions are:

1. 7000×4 + (29000 + 7000)÷9×3 = 40000
2. 8000×(14÷2)÷(1000-999) = 56000
3. 9000 - (35000÷7 + 4000)÷9 = 8000
4. 7000×7 - (8100÷9 + 1) = 48099
