Here we will explain what 24 mod 155 means and show how to calculate it. 24 mod 155 is short for 24 modulo 155 and it can also be called 24 modulus 155.
Modulo is the operation of finding the Remainder when you divide two numbers. Therefore, when you ask "What is 24 mod 155?" you are asking "What is the Remainder when you divide 24 by 155?".
We will show you two methods of finding 24 mod 155 (24 modulo 155). 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 24 is the Dividend, 155 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 24 mod 155 using the Modulo Method, we first divide the Dividend (24) by the Divisor (155).
Second, we multiply the Whole part of the Quotient in the previous step by the Divisor (155).
Then finally, we subtract the answer in the second step from the Dividend (24) to get the answer. Here is the math to illustrate how to get 24 mod 155 using our Modulo Method:
24 ÷ 155 ≈ 0.154839
0 × 155 = 0
24 - 0 = 24
Thus, the answer to "What is 24 mod 155?" is 24.
Modulus Method
To find 24 mod 155 using the Modulus Method, we first find the highest multiple of the Divisor (155) that is equal to or less than the Dividend (24).
Then, we subtract the highest Divisor multiple from the Dividend to get the answer to 24 modulus 155 (24 mod 155):
Multiples of 155 are 0, 155, 310, 465, etc. and the highest multiple of 155 equal to or less than 24 is 0. Therefore, to get the answer:
24 - 0 = 24
Thus, once again, the answer to "What is 24 mod 155?" is 24.
