Evaluate these quantities.

a) -17 mod 2

b) 144 mod 7

c) -101 mod 13

d) 199 mod 19

Step 1 :

In this problem we have to find the values of mod

(a)

Ans ; in this problem we have to find the value of -17 mod 2

Modulus statement are in the form

In this case a=-17 and b=2

This can be written as

.’.

Step 2 ;

(b) 144 mod 7

Ans ; in this problem we have to find the value of 144 mod 7

Modulus statement are in the form

In this case a=144 and b=7

This can be written as
