How a modulus function works?
At the basic level, the modulus of a number or expression is simply the value of the number or of the expression. For a positive number the modulus is the number, for 0 it is 0, and for a negative number, x, it is -x (which is positive).
When you add a positive and a negative number what do you get?
if the modulus (just the value ignoring the signs) of the negative number is larger than the positive number, adding the two will get you a negative number, if the positive number is larger, than modulus of a negative number you will have a positive. Can be easily demonstrated on a number line. yes
What is the flowchart for finding modulus of a number?
The modulus of a number is the units digit of that number in the base of the modulus. For example, counting to 10, modulus 3, we get... 0 01 12 23 04 15 26 07 18 29 010 1 The calculate the modulus of a number, subtract the (integer of the number divided by the modulus) times the modulus. As an expression, this is... Xmod Y = X - integer (X / Y) * Y Note: This works also for negative numbers. -3 mod 5 is 2. Check it, if you want. The result will be correct so long as the integer trunction is towards zero, i.e. the integer of -1.3 is -1, not -2. Most compilers do this correctly. If you are using a compiler such as C, the modulus operator (%) will do this for you... int a;a = 7 % 3; /* 7 mod 3 is 1 *.
Is a negative a whole numbers?
No. Whole numbers are counting numbers and zero.
Is a negative number an integer?
Integers are all of the real numbers that can be written without using a decimal or a fraction; i.e, they're the set of all positive and negative whole numbers plus zero.Integers have the following properties:i) 0 exists, and is the additive identity element; 0 + a = a for all a.ii) 1 exists, and is the multiplicative identity element; 1a = a for all a.iii) Addition and multiplication are both associative and commutative.iv) An additive inverse exists for all elements a, denoted as -a.v) Distributivity.vi) Adding or multiplying two integers yields another integer.From iv), we know that for each a > 0, there exists an additive inverse, -a, which must be less than 0, hence a negative number.So, there are integers that are negative numbers.But, not every negative number is an integer. There are negative numbers that must be expressed as a decimal or a fraction. For example, -0.5 isn't an integer, because, were you to not write it as a decimal, you would have to write it as a fraction: -1/2
