Answer:
90
- As, we see that 10 and 80 are the multiples of 10, the ones digit of the addend will remain 0 and we will add the tens digits of the numbers to obtain the tens digit of the addend.
- The digit at the tens place of 10 is 1 and the digit at the tens place of 80 is 8.
Adding, 1 + 8 = 9 - Placing 9 at the tens digit and 0 at the ones digit to obtain the addend, we have:
T O 9 0 - Hence,
T O 1 0 + 8 0 9 0
