Answer: The answer is 6.
Let’s solve the expression step – by – step. The expression is 6 – 5 × 2 + 10.
Based on the order of operations (PEMDAS/BODMAS), we do multiplication first. So, 5×2 = 10.
Now the expression becomes 6 – 10 + 10.
Then, for addition and subtraction, we work from left to right. 6−10 = – 4, and – 4+10 = 6.
So, the final answer is 6.

Answer:
To solve this puzzle right, we use the order of operations, remembered by PEMDAS:
- Parentheses
- Exponents
- Multiplication and Division (left – to – right)
- Addition and Subtraction (left – to – right)
Let’s apply PEMDAS to our equation.
Step – by – Step Solution
- Identify Operations: First, find the operations in the equation. Here, we have addition and multiplication. By PEMDAS, multiplication comes first.
- Do Multiplication First: Multiply 7×8 = 56.
- Put the Result Back: Substitute 56 back into the original equation, getting 6 + 56+9.
- Do the Addition: Add from left to right. 6+56 = 62, then 62 + 9 = 71.
Final Answer: 71
So, the right answer to the puzzle is 71.
