40 + 3 50 - 7 43 x 1
it's 100...
Numerators
DCI is 601. D = 500, C = 100, and I = 1, so 500 + 100 + 1 = 601.Now subtract 10 [X means 10], so 601- 10 = 591.So 500 = D, and then add 91. So 91 = 90 + 1. To get 90, do XC [100 - 10], then add 1 for XCI, so it is DXCI.
1. Subtract 25 2. Then subtract 6 3. Then subtract 12 4. Then subtract 2 5. Then subtract 10 6. Then subtract 15 7. Then subtract 7 8. Then add 3 X 1/2 9. Then add 8

109. C= 100, X = 10, I = 1 because I is before X you have to subtract it.
Subtract the numerator Subtract or add the numerator Subtract or add the numerator ex: 3/4-1/4=2/4 or 1/2 ex: 5/8 + 1/8= 6/8 or 3/4
i dont know u tell me?
The short answer is: Math. The long answer may not make a lot of sense to you unless you can figure it out for yourself, but I'll try by breaking it down into smaller steps. 4(5x + 8) = 4*5x + 4*8 = 20x + 32 5(20x + 32 + 9) = 5*20x + 5*41 = 100x + 205 (100x + 205 - 105)/100 = 100x/100 + 100/100 = x + 1 x + 1 -1 = x
Subtract a negative, eg 100 - (-1) = 101.
