A number “a” that exactly divides another number “b” is called a factor (or divisor) of “b”. Symbolically, this is often written as a I b, a divides b, where ac = b meaning that “a” is a factor/divisor of “b” or “b” is exactly divisible by “a” “c” times. ...
The identity property of multiplication states that there is a unique number, called the multiplicative identity (1) that, when multiplied by a number, results in the original number. a⋅1=aa⋅1=a For example, we have(−6)+0=−6(−6)+0=−6and23⋅1=23.23⋅1=23.There ...
Transitive Property: If x is equal to y and y is equal to z, then we can say that x = z. It is expressed as, x = y and y = z ⇒ x = z. Inverse Property: When an arithmetic operation is applied between a number and its inverse, we can get the identity. It is expressed...

There are many ways of encoding numbers, but here we'll only discuss decimal numbers which are encoded in a series of contiguous bytes (like binary floats and doubles) and which are described by a pair of parameters: a coefficient which is multiplied by ten raised to the power of an ...
The total count of consecutive odd numbers which sum up to form a perfect cube is equal to the number that is being cubed. To express $1^{3}$, only 1 odd number is involved. To express $2^{3}$, it involves the sum of 2 odd numbers, $3 + 5$. Facts about Perfect Cube...
