Here we will explain what 152 mod 3 means and show how to calculate it. 152 mod 3 is short for 152 modulo 3 and it can also be called 152 modulus 3.
Modulo is the operation of finding the Remainder when you divide two numbers. Therefore, when you ask "What is 152 mod 3?" you are asking "What is the Remainder when you divide 152 by 3?".
We will show you two methods of finding 152 mod 3 (152 modulo 3). 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 152 is the Dividend, 3 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 152 mod 3 using the Modulo Method, we first divide the Dividend (152) by the Divisor (3).
Second, we multiply the Whole part of the Quotient in the previous step by the Divisor (3).
Then finally, we subtract the answer in the second step from the Dividend (152) to get the answer. Here is the math to illustrate how to get 152 mod 3 using our Modulo Method:
152 ÷ 3 ≈ 50.666667
50 × 3 = 150
152 - 150 = 2
Thus, the answer to "What is 152 mod 3?" is 2.
Modulus Method
To find 152 mod 3 using the Modulus Method, we first find the highest multiple of the Divisor (3) that is equal to or less than the Dividend (152).
Then, we subtract the highest Divisor multiple from the Dividend to get the answer to 152 modulus 3 (152 mod 3):
Multiples of 3 are 0, 3, 6, 9, etc. and the highest multiple of 3 equal to or less than 152 is 150. Therefore, to get the answer:
152 - 150 = 2
Thus, once again, the answer to "What is 152 mod 3?" is 2.
