    149

    With regrouping: 1 borrow — from the tens

    277 − 128 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.
    6+10
    2 7(was 7, now 6)7 (was 7, now 17)
    −128
    149

    Column by column: 277 − 128

    • Ones: 7 is less than 8 — borrow 1 ten: tens 7 → 6; 17 − 8 = 9 — write 9.
    • Tens: after borrowing, 6; 6 − 2 = 4 — write 4.
    • Hundreds: 2 − 1 = 1 — write 1.

    277 − 128 = 149
