Unit digit of the square of 10036

Here we will show you two ways of finding the unit digit of the square of 10036. First, we will define what the unit digit of the square of 10036 means. Next, we will find the unit digit of the square of 10036 using the Rule Method, and then we will find the unit digit of the square of 10036 using the Math Method.

The last digit (one digit) of the product you get when you multiply 10036 by itself is the unit digit of the square of 10036.

Rule Method
The unit digit of any square will never be 2, 3, 7, or 8. It can be only 0, 1, 4, 5, 6, or 9. Furthermore, the unit digit of the square of a number depends on its units digit. In other words, the unit digit of the square of 10036 depends on 6, because that is the last digit in 10036. Here are the rules:

Rule A) If the unit digit of a number is 0, then the unit digit of the square of that number is 0.

Rule B) If the unit digit of a number is 1 or 9, then the unit digit of the square of that number is 1.

Rule C) If the unit digit of a number is 2 or 8, then the unit digit of the square of that number is 4.

Rule D) If the unit digit of a number is 5, then the unit digit of the square of that number is 5.

Rule E) If the unit digit of a number is 4 or 6, then the unit digit of the square of that number is 6.

Rule F) If the unit digit of a number is 3 or 7, then the unit digit of the square of that number is 9.

The unit digit of 10036 is 6, therefore Rule E applies, and the unit digit of the square of 10036 is 6.

Unit digit of the square of 10036 = 6

Math Method
The unit digit of the square of a number depends on its units digit with this method too. Here you multiply the unit digit of the number by itself, and then look at the unit digit of that product. Again, the unit digit of 10036 is 6, so you multiply 6 by itself, and then look at the unit digit to get the answer once again:

6 × 6 = 36
Unit digit of 36 is 6.
Unit digit of the square of 10036 = 6

Of course, instead of using either of the methods above, you can multiply 10036 by itself if you have the time or a calculator, and then identify the unit digit to get the answer to the unit digit of the square of 10036. We did that below to double-check that our answer is correct:

10036 × 10036 = 100721296
Unit digit of 100721296 is 6.
Unit digit of the square of 10036 = 6
