What is 200 − 63?

Answer

200 − 63 =
137

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

200 − 63 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: 200 − 63

  • Ones: 0 is less than 3 — borrow 1 hundred across the zero: hundreds 2 → 1, tens 0 → 9; 10 − 3 = 7 — write 7.
  • Tens: after borrowing, 9; 9 − 6 = 3 — write 3.
  • Hundreds: after borrowing, 1; nothing to subtract — write 1.

200 − 63 = 137

Second check: 200 − 137 = 63

FAQ

What is 200 − 63?

200 − 63 = 137

How do you check that 200 − 63 = 137?

Add the difference and the subtrahend: 137 + 63 = 200. Getting the minuend back means the difference is right.

How many times do you borrow in 200 − 63?

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 200 − 63?

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.
