- 858
6 56
what is the missing number?
To find the missing number in the equation:
73
- 858
6 56
We need to subtract 858 from 73. Let's break it down step-by-step:
1. Start with the rightmost column, which is the ones column. We subtract 8 from 3, but since 8 is greater than 3, we need to borrow from the tens column.
Add 10 (since there are 10 ones in a ten) to 3, making it 13.
Then subtract 8 from 13, which gives us 5 in the ones column.
2. In the tens column, we subtract 5 (since we borrowed) from 7, which gives us 2.
3. Now in the hundreds column, we subtract 8 from 6. We can't subtract 8 from 6, so we need to borrow from the thousands column.
Add 10 (since there are 10 tens in a hundred) to 6, making it 16.
Then subtract 8 from 16, which gives us 8 in the hundreds column.
4. Finally, in the thousands column, we subtract 8 from 7, which gives us 7.
So, the missing number is 765.
