Answer 2

77+18-4×6-4+9-4×5=77+18-24-4+9-20=104-48=76

Answer 3

To solve this expression, follow the order of operations, which is often remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

1. Solve multiplication: 4 × 6 = 24 and 4 × 5 = 20.
2. Perform addition and subtraction from left to right:

77 + 18 - 24 - 4 + 9 - 20

3. Perform the remaining additions and subtractions:

(77 + 18) - 24 - 4 + 9 - 20 95 - 24 - 4 + 9 - 20 71 - 4 + 9 - 20 67 + 9 - 20 76 - 20 56

So, the result of the expression is 56.
