Final answer:
By following the order of operations (PEMDAS) for mathematics, we find that the result of 'add 2+3, add 20, multiply by 3, add 9, divide by 6, and subtract 12' equals 2.
Step-by-step explanation:
To solve this problem, you need to follow the order of operations, also known as PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). There are no parentheses or exponents in this problem so we will start with addition.
First, add 2 + 3, which equals 5.
Second, add 20 to 5, which gives you 25.
Third, multiply the result by 3 (25 * 3), which equals 75.
Fourth, add 9 to 75, which equals 84.
Fifth, divide this by 6. So, 84 / 6 equals 14.
Last, subtract 12 from 14, which equals 2. Hence, the final answer is 2.
