1446 + 570 = 2016
Hindu
DLXX
In today's modern notation they represent: 1446
DLXX=570
Dlxx d = 500, l = 50, x = 10
Just tackle the problem in the same way as you would work out a problem in long multiplication and then add up the products as follows:- C times DLXX = (LVII) => 100*570 = 57,000 XXX times DLXX = (XVII)C => 333*570 = 17,100 V times DLXX = (II)DCCCL => 5*570 = 2,850 III times DLXX = (I)DCCX => 3*570 = 1,710 (LVII)+(XVII)C+(II)DCCCL+(I)DCCX = (LXXVIII)DCLX 57,000+17,100+2,850+1,710 = 78,660 Note that numerals within brackets indicate multiplication by 1,000.
76 plus 54 plus 92 plus 88 plus 76 plus 88 plus 75 plus 93 plus 92 plus 68 plus 88 plus 76 plus 76 plus 88 plus 80 plus 70 plus 88plus 72 equal 1,440
The answer is 672.
27x3+6=87.
132
It is 77
