Spiegazione passo passo

1. Rewrite the numbers from top to bottom, aligned by their place values

Place value	hundreds	tens	ones

	1	2	6
-		9	5

2. Subtract the numbers using long subtraction method

Subtract the numbers in the ones column from the top number:
6-5=1

Place value	hundreds	tens	ones

	1	2	6
-		9	5
			1

Because the upper digit (2) in the tens column is too small to get a positive difference, borrow 1 from the digit (1) in the next number place which becomes (0) and get (12).

Place value	hundreds	tens	ones
	0	12
	1	2	6
-		9	5
			1

Subtract the numbers in the tens column from the top number:
12-9=3

Place value	hundreds	tens	ones
	0	12
	1	2	6
-		9	5
		3	1

Write 0 in the hundreds place.

Place value	hundreds	tens	ones
	0	12
	1	2	6
-		9	5
	0	3	1

The solution is: 31
