Priya has 145 mangoes. She gives 78 to her neighbour and later buys 96 more. How many mangoes does she have now? Show steps and indicate any carries during addition/subtraction.

Step-by-step solution

1. Subtracting 78 from 145:
2. Units: $5$ minus $8$ needs borrow. Borrow from tens, tens becomes $4$, units become $15$. $15-8=7$.
3. Tens: $4$ minus $7$ needs borrow. Borrow from hundreds, hundreds becomes $0$, tens become $14$. $14-7=7$.
4. Hundreds: $0$ minus $0=0$. Result of subtraction is $67$.
5. Adding 96 to 67:
6. Units: $7+6=13$ → write 3, carry 1.
7. Tens: $6+9+1=16$ → write 6, carry 1 (to hundreds).
8. Hundreds: $0+0+1=1$.
9. Final count of mangoes: $163$.
10. Carries occurred during addition (once) but not during subtraction.
