Here we will explain what 138 mod 174 means and show how to calculate it. 138 mod 174 is short for 138 modulo 174 and it can also be called 138 modulus 174.
Modulo is the operation of finding the Remainder when you divide two numbers. Therefore, when you ask "What is 138 mod 174?" you are asking "What is the Remainder when you divide 138 by 174?".
We will show you two methods of finding 138 mod 174 (138 modulo 174). 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 138 is the Dividend, 174 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 138 mod 174 using the Modulo Method, we first divide the Dividend (138) by the Divisor (174).
Second, we multiply the Whole part of the Quotient in the previous step by the Divisor (174).
Then finally, we subtract the answer in the second step from the Dividend (138) to get the answer. Here is the math to illustrate how to get 138 mod 174 using our Modulo Method:
138 ÷ 174 ≈ 0.793103
0 × 174 = 0
138 - 0 = 138
Thus, the answer to "What is 138 mod 174?" is 138.
Modulus Method
To find 138 mod 174 using the Modulus Method, we first find the highest multiple of the Divisor (174) that is equal to or less than the Dividend (138).
Then, we subtract the highest Divisor multiple from the Dividend to get the answer to 138 modulus 174 (138 mod 174):
Multiples of 174 are 0, 174, 348, 522, etc. and the highest multiple of 174 equal to or less than 138 is 0. Therefore, to get the answer:
138 - 0 = 138
Thus, once again, the answer to "What is 138 mod 174?" is 138.
