Congruence.
Let m be an integer greater than 1. If x and y are integers, then x is congruent to y modulo m if x — y is divisible by m. It can be represented as
Calculation:
It is known that, [x] + [y] = [x+y].
Then, the value of the expression becomes as follows.
[43] + [31] = [43 + 31] = [74]
Since
Therefore, the value of the expression is [8].
