In either a finite set with 11 elements, we obtain the following when multiplying by 4 modulo (11).
If a material cannot be broken down into a simpler form, it is regarded as an element. Their unique atomic number can be used to identify them. According their atomic number, the elements are grouped in the periodic table, and those with similar qualities may be noted.
7*7+17*7+1 modulo(11)=[7*7 modulo(11)+17*7 modulo(11)+1 modulo(11)]modulo(11)
=[49 modulo(11)+119 modulo(11)+1 modulo(11)]modulo(11)
=[5+9 +1]modulo(11)
=15 modulo(11)
=4 modulo(11)
7*7+17*7+1 modulo(11)=4 modulo(11)
