Question

Try and change these numbers into special numbers —
(a) 28
(b) 132
(c) 273

Answer 1

(a)
Take number 28, turn it in the reverse order to get 82.
Add them together: 28 + 82 = 110
But this is not a special number because when we reverse its order, we get 011.
Now, we add: 110 + 011 = 121
When we reverse its order, we get 121.
Thus, it is a special number.

(b)
Take the number 132, turn it in the reverse order to get 231.
Add them together: 132 + 231 = 363
When we reverse its order, we get 363.
Thus, we get the special number as required.

(c)
Take the number 273, turn it in the reverse order to get 372
Add them together: 273 + 372 = 645
But this is not a special number because when we reverse its order, we get 546.
Now, if we subtract them, we get
645 − 546 = 99
When we reverse its order, we get 99, which is a special number.
