Answer 2

To solve this expression, we need to follow the order of operations, which is often represented by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's break down the expression step by step:

(7 · 4 + 28 : 7) + 14 : 2 – 6 · 6 + (18 – 9) · 3 + 2 · 6

Step 1: Solve the expressions inside parentheses: (7 · 4 + 28 : 7) = (28 + 28 : 7) = (28 + 4) = 32

So the expression becomes: 32 + 14 : 2 – 6 · 6 + (18 – 9) · 3 + 2 · 6

Step 2: Perform division and multiplication from left to right: 32 + 14 : 2 = 32 + 7 = 39

The expression becomes: 39 – 6 · 6 + (18 – 9) · 3 + 2 · 6

Step 3: Solve the subtraction and addition from left to right: 39 – 6 · 6 = 39 – 36 = 3

The expression becomes: 3 + (18 – 9) · 3 + 2 · 6

Step 4: Solve the parentheses: (18 – 9) = 9

The expression becomes: 3 + 9 · 3 + 2 · 6

Step 5: Perform multiplication from left to right: 9 · 3 = 27 2 · 6 = 12

The expression becomes: 3 + 27 + 12

Step 6: Perform addition: 3 + 27 + 12 = 42

Therefore, the result of the expression is 42.
