 Hello and welcome to the session. In this session we discussed the following question which says, write the following as a Hindu-Arabic numeral XXXVI. Let's move on to the solution. We need to write XXXVI as a Hindu-Arabic numeral. Now we know that in Hindu-Arabic numeral the value for X is 10. The value for V is 5 and the value for I is 1. We know that the repetition of a symbol in a Roman numeral means addition. So as you can see in this expression X is repeated 3 times. So XXX is equal to 10 plus 10 plus 10 which is equal to 30. Now let's see what would be the value for VI. Now V means 5 and I means 1. So a smaller numeral is written to the right of a larger numeral. So in this case the smaller numeral is added to the larger numeral. So this would be equal to 5 plus 1 which is equal to 6. Now XXXVI would be equal to the value of XXX which is 30 plus the value for VI which is 6 and this is equal to 36. So we write XXXVI in Hindu-Arabic numeral as 36. This is our final answer. This completes the session. Hope you have understood the solution of this question.
