Perform the indicated operations:
aliina [53]

Answer and Explanation:

To find : Perform the indicated operations?

Solution :

Modular math is defined as

\frac{A}{B}=Q\text{ remainder } R

or A\times Q+R=B

Where, A is the dividend

B is the divisor

Q is the quotient

R is the remainder  

The solution is A mod B = R

Now, We perform same in every case

1) (9+6), \mod 5

We can direct add the term,

15 \mod 5

Now, we divide 15 by 5 and see the remainder

5\times 3+0=15

Remainder is 0.

So,  15 \mod 5=0

2) (7-11), \mod 12

We can direct subtract the term,

-4 \mod 12

Now, we divide -4 by 12 and see the remainder

12\times (-1)+8=-4

Remainder is 8.

So,  -4 \mod 12=8

3) (4\times 3), \mod 5

We can direct multiply the term,

12 \mod 5

Now, we divide 12 by 5 and see the remainder

5\times 2+2=12

Remainder is 2.

So, 12 \mod 5=2

4) (1\div 2), \mod 5

We can direct divide the term,

0.5 \mod 5

Now, we divide 0.5 by 5 and see the remainder

5\times 0+0.5=0.5

Remainder is 0.5.

So,  0.5 \mod 5=0.5
