What Is a Unit Digit?
The unit digit is the last digit of a number. For example, in 458, the unit digit is 8. In 1230, the unit digit is 0.
In exams, you may be asked to find the unit digit of large powers. Sometimes, multiplication or addition is involved. These questions look lengthy, but are easy if the pattern is known.
Why Unit Digit Questions Are Important?
Unit digit questions are quick to solve. They save time in exams. They do not need rough work. With practice, answers can be found mentally.
In SSC GD Maths Question 2026, these questions are expected because they test logical thinking and number sense. Many students lose marks due to confusion. But with clear steps, mistakes can be avoided.
Basic Rules of Unit Digit
To solve unit digit questions, some basic rules should be remembered.
-
Only the last digit affects the unit digit.
-
Large numbers can be ignored except for their last digit.
-
Powers follow a repeating pattern.
These simple ideas help in solving most questions from this topic.
Unit Digit of Powers
This is one of the most common question types. Let us understand with examples.
Example 1
The unit digit pattern of powers of 2 is:
2, 4, 8, 6
This pattern repeats every 4 steps.
Now divide 35 by 4.
Remainder = 3
The 3rd number in the pattern is 8.
So, the unit digit is 8.
This type of question is common in SSC GD Maths Question 2026.
Example 2
The unit digit pattern of 7 is:
7, 9, 3, 1
This also repeats after 4 steps.
22 ÷ 4 gives a remainder 2.
The 2nd digit in the pattern is 9.
So, the unit digit is 9.
Unit Digit of Multiplication
In multiplication, only the unit digits of numbers matter.
Example
Find the unit digit of 234×67.
The unit digit of 234 is 4.
The unit digit of 67 is 7.
Now multiply 4 × 7 = 28.
The unit digit of 28 is 8.
So, the answer is 8.
Such questions are often seen in SSC GD Maths Question 2026 practice sets.
Unit Digit of Multiple Numbers
Sometimes more than two numbers are multiplied.
Example
Find the unit digit of 12×15×18.
Unit digits are:
12 → 2
15 → 5
18 → 8
Now multiply step by step.
2 × 5 = 10
10 × 8 = 80
The unit digit is 0.
Unit Digit of Large Expressions
Large expressions look difficult, but are easy if broken into parts.
Example
This approach is useful for SSC GD Maths Question 2026.
Unit Digit of Addition and Subtraction
For addition and subtraction, add or subtract the unit digits only.
Example
Find the unit digit of 456+789.
Unit digits are 6 and 9.
6 + 9 = 15
The unit digit is 5.
Example
Find the unit digit of 803−278.
Unit digits are 3 and 8.
3 - 8 is not possible directly.
Borrow from the tens place.
803 - 278 = 525
Unit digit is 5.
