54

With regrouping: 1 borrow — from the tens

93 − 39 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.
		8	+10
		9(was 9, now 8)	3 (was 3, now 13)
	−	3	9
		5	4

Column by column: 93 − 39

Ones: 3 is less than 9 — borrow 1 ten: tens 9 → 8; 13 − 9 = 4 — write 4.
Tens: after borrowing, 8; 8 − 3 = 5 — write 5.

93 − 39 = 54
