Answer 1

6*7=35

(34+18)+2=54

7*6=42

(18+2)+34+2=56

Answer 2

Let's simplify the given expressions:

1. 6 * 7 * (34 + 18) + 2: First, evaluate the expression within the parentheses: 34 + 18 = 52. Now, substitute the result back into the expression: 6 * 7 * 52 + 2. Finally, perform the multiplication: 6 * 7 * 52 = 2184. The final expression becomes: 2184 + 2 = 2186.

2. 6 + 7 * (18 + 2) + 34: Again, start by evaluating the expression within the parentheses: 18 + 2 = 20. Now, substitute the result back into the expression: 6 + 7 * 20 + 34. Perform the multiplication: 7 * 20 = 140. The expression becomes: 6 + 140 + 34. Add the numbers together: 6 + 140 = 146, then 146 + 34 = 180.

3. 7 * 6 * (18 + 2) + 34 + 2: Evaluate the expression within the parentheses: 18 + 2 = 20. Substitute the result back into the expression: 7 * 6 * 20 + 34 + 2. Perform the multiplication: 7 * 6 * 20 = 840. The expression becomes: 840 + 34 + 2. Add the numbers together: 840 + 34 = 874, then 874 + 2 = 876.

To summarize:

1. 6 * 7 * (34 + 18) + 2 = 2186.
2. 6 + 7 * (18 + 2) + 34 = 180.
3. 7 * 6 * (18 + 2) + 34 + 2 = 876.
