What is 402 − 26?

Answer

402 − 26 =
376

With regrouping across a zero: 2 borrows — there are no tens to borrow from, so 1 hundred becomes 10 tens, and 1 ten goes to the ones

402 − 26 in a column. Above the columns: the values after borrowing — a crossed-out digit is replaced by the number above it; +10 marks a column that received a borrowed ten.

Column by column: 402 − 26

  • Ones: 2 is less than 6 — borrow 1 hundred across the zero: hundreds 4 → 3, tens 0 → 9; 12 − 6 = 6 — write 6.
  • Tens: after borrowing, 9; 9 − 2 = 7 — write 7.
  • Hundreds: after borrowing, 3; nothing to subtract — write 3.

402 − 26 = 376

Second check: 402 − 376 = 26

Add the difference and the subtrahend: 376 + 26 = 402. Getting the minuend back means the difference is right.

How many times do you borrow in 402 − 26?

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

Why does 0 become 9 when borrowing in 402 − 26?

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.
