Here we will explain what 71 mod 5 means and show how to calculate it. 71 mod 5 is short for 71 modulo 5 and it can also be called 71 modulus 5.
Modulo is the operation of finding the Remainder when you divide two numbers. Therefore, when you ask "What is 71 mod 5?" you are asking "What is the Remainder when you divide 71 by 5?".
We will show you two methods of finding 71 mod 5 (71 modulo 5). To differentiate our methods, we will call them the "Modulo Method" and the "Modulus Method".
Before we continue, we remind you of what the different parts of a division problem are called so you can follow along: Dividend / Divisor = Quotient and in this case 71 is the Dividend, 5 is the Divisor, and the answer is called the Quotient.
Furthermore, the Quotient x.y has two parts: x to the left of the decimal point is the Whole part, and y to the right of the decimal point is the Fractional part.
Modulo Method
To find 71 mod 5 using the Modulo Method, we first divide the Dividend (71) by the Divisor (5).
Second, we multiply the Whole part of the Quotient in the previous step by the Divisor (5).
Then finally, we subtract the answer in the second step from the Dividend (71) to get the answer. Here is the math to illustrate how to get 71 mod 5 using our Modulo Method:
71 ÷ 5 = 14.2
14 × 5 = 70
71 - 70 = 1
Thus, the answer to "What is 71 mod 5?" is 1.
Modulus Method
To find 71 mod 5 using the Modulus Method, we first find the highest multiple of the Divisor (5) that is equal to or less than the Dividend (71).
Then, we subtract the highest Divisor multiple from the Dividend to get the answer to 71 modulus 5 (71 mod 5):
Multiples of 5 are 0, 5, 10, 15, etc. and the highest multiple of 5 equal to or less than 71 is 70. Therefore, to get the answer:
71 - 70 = 1
Thus, once again, the answer to "What is 71 mod 5?" is 1.
