When solving mathematical expressions, you must follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication/Division left to right, Addition/Subtraction left to right) to get the correct answer; for example, in the expression 9 - 1 * 9 - 1, you must multiply 1 * 9 first (getting 9), then subtract 9 from 9 (getting 0), and finally subtract 1 (getting -1), rather than solving left to right which would give an incorrect answer of 64.

Hello, respectable audience. This question is very simple, but remember that it's a math trap.
Most people are trapped. About 90% are trapped while solving this tricky question because they will solve just 9 - 1 as 8.
Here they can put multiplication and 9 - 1 is 8. So, they will get 8 multiplied by 8, which will be equal to 64. How they will get 64? Because their method is 9 - 1 is 8.
And here 9 - 1, which will be equal to 8. So, after multiplying 8 with 8, we will get 64. But 64 is not correct. So, what we have to do to get it correctly, we have to resolve this question according to PEMDAS rule. So, 9 - 1 * 9 - 1 can be solved by obeying PEMDAS rule. Here is P, here is E, M, D, A, S.
So, these are the six steps.
If we follow PEMDAS, we will get correct answer. P stands for parentheses. Here you are looking parentheses. So, 9 - 1 multiplied by it is 8. Okay? Now, exponent is missing.
Multiplication, yes, we have multiplication. So, 9 - 1 is a white.
Because first of all, we have to solve multiplication. So, 9 - 1 * 8, it will be equal to 8. So, 9 - 1, 9 - 8, 8 will be equal to 1. That is our answer according to PEMDAS rule. Thank you for your support.
