Here we will explain what 180 mod 161 means and show how to calculate it. 180 mod 161 is short for 180 modulo 161 and it can also be called 180 modulus 161.
Modulo is the operation of finding the Remainder when you divide two numbers. Therefore, when you ask "What is 180 mod 161?" you are asking "What is the Remainder when you divide 180 by 161?".
We will show you two methods of finding 180 mod 161 (180 modulo 161). 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 180 is the Dividend, 161 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 180 mod 161 using the Modulo Method, we first divide the Dividend (180) by the Divisor (161).
Second, we multiply the Whole part of the Quotient in the previous step by the Divisor (161).
Then finally, we subtract the answer in the second step from the Dividend (180) to get the answer. Here is the math to illustrate how to get 180 mod 161 using our Modulo Method:
180 ÷ 161 ≈ 1.118012
1 × 161 = 161
180 - 161 = 19
Thus, the answer to "What is 180 mod 161?" is 19.
Modulus Method
To find 180 mod 161 using the Modulus Method, we first find the highest multiple of the Divisor (161) that is equal to or less than the Dividend (180).
Then, we subtract the highest Divisor multiple from the Dividend to get the answer to 180 modulus 161 (180 mod 161):
Multiples of 161 are 0, 161, 322, 483, etc. and the highest multiple of 161 equal to or less than 180 is 161. Therefore, to get the answer:
180 - 161 = 19
Thus, once again, the answer to "What is 180 mod 161?" is 19.
