Simplify the following:
81 mod 11
Also, does 11 divide 81?
Define modulus:
Remainder of a ÷ b
In this case, a = 81 and b = 11
Calculate whole number part:
11 goes into 81 a total of 7 times
11 x 7 = 77
Calculate remainder part:
Remainder = a - whole number
Remainder = 81 - 77
Final Answer
81 mod 11 ≡ 4
This means that 11 does not divide 81 → 11∤81
This means that 11 does not divide 81 → 11∤81
