Here we will explain what 80 mod 200 means and show how to calculate it. 80 mod 200 is short for 80 modulo 200 and it can also be called 80 modulus 200.
Modulo is the operation of finding the Remainder when you divide two numbers. Therefore, when you ask "What is 80 mod 200?" you are asking "What is the Remainder when you divide 80 by 200?".
We will show you two methods of finding 80 mod 200 (80 modulo 200). 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 80 is the Dividend, 200 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 80 mod 200 using the Modulo Method, we first divide the Dividend (80) by the Divisor (200).
Second, we multiply the Whole part of the Quotient in the previous step by the Divisor (200).
Then finally, we subtract the answer in the second step from the Dividend (80) to get the answer. Here is the math to illustrate how to get 80 mod 200 using our Modulo Method:
80 ÷ 200 = 0.4
0 × 200 = 0
80 - 0 = 80
Thus, the answer to "What is 80 mod 200?" is 80.
Modulus Method
To find 80 mod 200 using the Modulus Method, we first find the highest multiple of the Divisor (200) that is equal to or less than the Dividend (80).
Then, we subtract the highest Divisor multiple from the Dividend to get the answer to 80 modulus 200 (80 mod 200):
Multiples of 200 are 0, 200, 400, 600, etc. and the highest multiple of 200 equal to or less than 80 is 0. Therefore, to get the answer:
80 - 0 = 80
Thus, once again, the answer to "What is 80 mod 200?" is 80.
