c=100,M=1000 so cm =100-1000 (answer. c)

## Ans 2:

Class : Class 5
The correcr answer is B CM = 1000 – 100.

## Ans 3:

Class : Class 5
The correct answer would be option C because CM = 900. C=100, M=1000. So, the smaller no. is in the beginning, it will be minus. So, 1000-100 is the correct ans.

Class : Class 4
A

## Ans 6:

Class : Class 4
If there is C before M that means that we are subtracting 100 from 1000 . We write it as 1000 - 100. Answer : B

Class : Class 2
CM=1000-100

Class : Class 4
A

## Ans 9:

Class : Class 5
The answer is B because CM=C-M=C(100)-M(1000)We cannot subtract 100-1000 So the formula should be 1000-100 l Therefore, TH H T O 1 0 0 0 - 1 0 0 ----------------------- 9 0 0 So, B is the right answer.
