Simplify the following:
20 mod 11
Also, does 11 divide 20?
Define modulus:
Remainder of a ÷ b
In this case, a = 20 and b = 11
Calculate whole number part:
11 goes into 20 a total of 1 times
11 x 1 = 11
Calculate remainder part:
Remainder = a - whole number
Remainder = 20 - 11
Final Answer
20 mod 11 ≡ 9
This means that 11 does not divide 20 → 11∤20
This means that 11 does not divide 20 → 11∤20
