Question

Form a two digit number whose unit's place in x and ten's place is y
​

Answer 1

Answer:

10y + x

Step-by-step explanation:

The required number will be 10y + x

If you think of a number with the digits (say) 5 in the ten's place and 3 in the one's place, we can easily see that the number is 53.

However, the number is obtained by (5x10) + (3x1) = 50 + 3 = 53

In general, the value of a number depends on the place value more than the face value.

e.g. In the number 53, the face value of 5 is 5 but the place value of 5 is 50.

Hope this helps!
