Pl clock arithmetic will mark brainiest .

clock arithmetic

calculate = a) 8 - 11 (12 clock ) (a) 9 + 10 (18-clock)
b) 4 divide 9 ( 12 clock ) (b) 2 divide 5 (13-clock)
c) 7 - 6 ( 12 clock ) (c) 1 - 5 ( 37 - clock )
d) 8 divide 5 ( 12 clock ) ( d ) 3 * 9 ( 18 clock )

i know this is too much but plz
plz give answer like this = 4 + 9 = 13, 13 - 12 = 1

see below

Step-by-step explanation:

In clock arithmetics, your answer has to be in the range 0-N where N is the number of hours in your given clock.

If the initial answer < 0, you add N until you get >=0

If the initial answer >= N, subtract N until you get < N.

a) 8 - 11 (12 clock ) = -3, then -3 + 12 = 9

(a) 9 + 10 (18-clock)  = 19, then 19 - 18 = 1

B) 4 Divide 9 ( 12 clock ) , 4/9

(B) 2 Divide 5 (13-clock)  , 2/5

C) 7 - 6 ( 12 clock ) = 1, fine.

(C) 1 - 5 ( 37 - clock )  = -4, then -4 + 37 = 33

D) 8 Divide 5 ( 12 clock )  = 8/5, fine

( D ) 3 * 9 ( 18 clock ) =27, then 27 - 18 = 9
