To solve the expression 29 - 30 ÷ 5 × 3 + 12, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).
1. Start with the division: 30 ÷ 5 = 6.
2. Next, perform the multiplication: 6 × 3 = 18.
3. Then, perform the addition and subtraction from left to right: 29 - 18 + 12.
4. Perform the subtraction: 29 - 18 = 11.
5. Finally, perform the addition: 11 + 12 = 23.
Therefore, the solution to the expression 29 - 30 ÷ 5 × 3 + 12 is 23.
