What is 10,000 − 136?

Answer

10,000 − 136 =

9,864

With regrouping across zeros: 4 borrows — 3 zeros in a row, so 1 ten thousand is passed down, each zero becomes 9, and 1 ten goes to the ones

Ones: 0 is less than 6 — borrow 1 ten thousand across the zero: ten thousands 1 → 0, thousands 0 → 9, hundreds 0 → 9, tens 0 → 9; 10 − 6 = 4 — write 4.
Tens: after borrowing, 9; 9 − 3 = 6 — write 6.
Hundreds: after borrowing, 9; 9 − 1 = 8 — write 8.
Thousands: after borrowing, 9; nothing to subtract — write 9.
Ten thousands: after borrowing, 0 — a leading zero is not written.

10,000 − 136 = 9,864

Second check: 10,000 − 9,864 = 136

Add the difference and the subtrahend: 9,864 + 136 = 10,000. Getting the minuend back means the difference is right.

4 borrows: each time the top digit was smaller than the one below it, 1 was borrowed from the column on the left.

The zero has nothing to lend, so it first borrows 1 from its left neighbour and becomes 10; then it lends 1 to the column on its right and keeps 9.
