There is only one number that's equal to 81. That number is 81.
There are many other sets of two or more numbers that you can manipulate
with an arithmetic operation and produce 81 as the result. For example:
Addition: 27 + 54 = 81
Subtraction: 175 - 94 = 81
Multiplication: 3 x 27 = 81
Division: 567 / 7 = 81
But none of those other numbers is "equal" to 81.

Addition: 27 + 54 = 81, or more easily would be 80 + 1 = 81, and so on.
Subtraction: 175 - 94 = 81, or more easily would be 82 - 1 = 81, and so on.
Multiplication: 3 x 27 = 81, or 9 x 9 = 81, and so on.
Division: 567 / 7 = 81, or 81 / 1 = 81, and so on.
“/“, is just another way to put the division sign by the way.
