# Write missing tens or ones digit. 42 + 3⎕ = 75

- 3
- 4
- 5
- 6

Hint:

### Find by partial sum method.

To find partial sums add the digits in tens place and ones place seperately.

## The correct answer is: 3

### Since The missing digit place value is ones digit add the digits in tens place first

Partial sum of 42 + 3⎕ = 75

Step 1 : Add digits in tens place seperately:

40

+ 30

___________

70

Here, 40 + 30 = 70

Step 2 : Add digits in ones places

since 1 is carried over, the tens digit place becomes 20

02

+ 0 _

_______

05

= 02 + x = 05

x = 05 - 02

x = 03

Thus , the missing digit is 03, 42 + 33 = 75.
