# Subtraction Placing the Numbers

Learn how to do subtraction placing the numbers in columns. Subtract from two-digit numbers by arranging and placing the numbers correctly in tens and ones column.

1. Subtract 23 from 89 (by placing the numbers in column).

Solution:

Subtract 89 - 23 arrange by placing the numbers in column

T         O

8         9

-    2         3

6        6

(i) Given numbers are written in column form.

(ii) Subtraction of digits at one’s place, 9 – 3 = 6 ones.

(iii) Subtraction of digits at ten’s place, 8 – 2 = 6 tens.

(iv) Subtracted sum = 6 tens + 6 ones = 60 + 6 = 66

(v) Therefore, 89 – 23 = 66

2. Subtract 46 from 78 (by placing the numbers in column).

Solution:

Subtract 78 - 46 arrange by placing the numbers in column.

T         O

7         8

-    4         6

3        2

(i) Given numbers are written in column form.

(ii) Subtraction of digits at one’s place, 8 – 6 = 2 ones.

(iii) Subtraction of digits at ten’s place, 7 – 4 = 3 tens.

(iv) Subtracted sum = 3 tens + 2 ones = 30 + 2 = 32

(v) Therefore, 78 - 46 = 32

3. Subtract 23 from 94 (by placing the numbers in column).

Solution:

Subtract 94 - 23 arrange by placing the numbers in column.

T         O

9         4

-    2         3

7        1

(i) Given numbers are written in column form.

(ii) Subtraction of digits at one’s place, 4 – 3 = 1 one.

(iii) Subtraction of digits at ten’s place, 9 – 2 = 7 tens.

(iv) Subtracted sum = 7 tens + 1 one = 70 + 1 = 71

(v) Therefore, 94 - 23 = 71

The examples will help us to solve different types of problems of 2-digit subtraction placing the numbers in vertical order.
