Answer 3

To solve the expression, follow 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)

The expression you provided is:

7 * 6 + [90 - 67] - 5 * 4

Let's solve it step by step:

1. Parentheses/Brackets: [90 - 67] = 23

2. Multiplication and Division (from left to right): 7 * 6 = 42 5 * 4 = 20

3. Addition and Subtraction (from left to right): 42 + 23 - 20

Now, combine the results:

42 + 23 - 20 = 45

So, the value of the expression is 45.
