3 % 7 = 3 How? Well we know that modulo returns the remainder. 3 / 7 = 0.428 means the highest number that can be multiplied by 7 to get 3 or a value close to 3 is 0. 0 times 7 = 0. which leaves 3 as our remainder value (0+3=3) so 3 is our answer.
The mod function gives the remainder above the greatest multiple less than the first parameter. If it were 7 mod 3, then 6 is the greatest multiple less than 7, so 1 is the answer (7-6) As it is -7, then -9 is the greatest mulitiple less than -7, so 2 is the answer (-7- -9, or -7+9)
Modulus operator gives you the result in 'reduced residue system'. For example for mod 5 there are 5 integers counted: 0,1,2,3,4. In fact 19=12=5=-2=-9 (mod 7). The main difference that the answer is given by programming languages by 'reduced residue system'.
7 mod 3 = 1. 7^2 mod 3=49 mod 3 = 1 [ 7 mod 3]^2 mod 3=1^2 mod 3 = 2 mod 3 = 2. you have to find 7 mod 3 first and then square it. 7^1000 mod 3 = (2*3+1)^1000 mod 3 . if you expand (2*3+1)^1000, then every term will be multiple of 3 except last term, which is 1^1000, so . 7^1000 mod 3 = (2*3+1)^1000 mod 3 = 1^1000 mod 3= 1 mod 3=1
remainder = 3 % 7; // equals 3. The best way to determine why your code is not doing what you think is to step through your code using a debugger. All the multiples of 3 & 7 will be multiples of 21, i.e. 21, 42, 63, 84.
Now, for 7 bananas and 6 people in group, you then will have 7 mod 6 = 1, this because you gave 6 people 1 banana each, and 1 banana is the remainder. For 12 mod 6 or 12 bananas shared on 6 people, each one will have two bananas, and the remainder is then 0.
3 equals 15 mod 4. – Paul Fisher. Commented Jun 13, 2009 at 17:02. 2. You're probably thinking that (15 ...
It all falls back to the definition of modulus: It is the remainder, for example, 7 mod 3 = 1. This because 7 = 3(2) + 1, in which 1 is the remainder. To do this process on a simple calculator do the following: Take the dividend (7) and divide by the divisor (3), note the answer and discard all the decimals -> example 7/3 = 2.3333333, only ...
