If the sum of 7 and 9 is more than 12 add 3; if less, subtract 2. What is the correct answer?
Fundamental operations are the basis of mathematics. They include four operations: addition, subtraction, multiplication and division. Let's solve a problem based on these.
Answer: The sum of 7 and 9 is greater than 12, so the correct answer is 19.
Let's understand the solution in detail.
First, we check if the sum of 7 and 9 is more than 12 or not.
Here, we see that (7 + 9) = 16. So, 16 > 12.
Hence, we add 3 to the result.
16 + 3 = 19
Therefore, as the sum of 7 and 9 is greater than 12, the correct answer is 19.
