For any two integers, a "+" B = a + B-1, a "×" B = axb-1, Find the value of 4 "×" [(6 "+" 8) "+ (3" × "5)]
(6“+”8)=6+8-1=13
(3“×”5)=3*5-1=14
13"+"14=13+14-1=26
4"x"26=4*26-1=103
So:
4“×”[(6“+”8)“+”(3“×”5)]=103
For integers a, B, C and D, the expression │ ABCD │ denotes the operation AC BD, and 1 is known
It can be seen from the meaning of the title:
│1b4c│=14-bc
And because a, B, C, D are integers
So 1
For the integer ABCD, define the operation ABCD = AC – BD, and find the value of 1234
For the integer ABCD, define the operation ABCD = AC – BD, find 1234 = 13-24 = - 11
