Assignment:
Construct addition and multiplication tables for arithmetic modulo 11. For example, 7 + 8 mod 11 is 4 and 7*8 mod 11 is 1 so the entry in row 7, column 8 would be 4 for the addition table and 1 for the multiplication table. Use your tables to solve each of the following congruences:
a. 3x+2≡8 (mod11)
b. 3x-5≡2 (mod11)
c. 2x2 + x + 8≡0 (mod 11)
