You cannot subtract 8 from 2 in the ones, so borrow from the tens to make 12 - 8 = 4. After borrowing, the tens become 2 - 7, which needs another borrow from the hundreds, leading to the correct answer of 254.

In the ones, 14 - 7 = 7 after borrowing. The tens column becomes 0 - 5, which needs another borrow, giving 10 - 5 = 5, and the hundreds become 5 - 3 = 2, so the answer is 257.

Subtracting from 800 means borrowing across two zeros. The hundreds, tens, and ones become 7, 9, and 10, so 7-9-10 minus 4-5-6 gives 344.

Line up the digits and subtract column by column: 5 - 2 = 3 in the ones, 4 - 1 = 3 in the tens, and 7 - 3 = 4 in the hundreds. No borrowing is needed, so the difference is 433.

Ones: 13 - 8 = 5 after borrowing 1 from the tens. Tens: 5 - 4 = 1. Hundreds: 9 - 5 = 4. The result is 415.

Because 500 has zeros in the tens and ones, you must borrow across both. After regrouping, you compute 4-9-10 minus 2-3-7, which gives 263.

Ones: 11 - 9 = 2 after borrowing from the tens. Tens: 6 - 5 = 1. Hundreds: 8 - 4 = 4. The difference is 412.

True. The ones column needs 4 - 9, which is impossible without borrowing, so you take 1 from the tens place to make it 14 - 9.

False. Subtracting 350 from 900 leaves 550, since 9 hundreds minus 3 hundreds is 6 hundreds and you must borrow once for the tens column.

True. Subtracting 431 from 756 column by column gives 5 ones, 2 tens, and 3 hundreds, which is exactly 325.
