A negative minus a negative is equal to another negative number, a positive number or zero, depending upon the numbers in the equation. Subtracting a negative number from another negative number is the same thing as adding a positive number.
Continue ReadingIf the negative number being subtracted is the same as the number from which it is subtracted, the answer is zero. For example, -5 - (-5) = 0. If the negative number being subtracted is greater in value than the negative number from which it is being subtracted, the answer is negative. For example, -10 - (-8) = -2. If, however, the negative number being subtracted is less in value than the negative number from which it is being subtracted, the answer is a positive number. For example, -10 - (-12) = 2.

To determine the number of possibilities, each place digit has to be evaluated independently to see how many numbers could fit there and then all are multiplied together.
Full Answer >Use a random number generator by providing a range of numbers from which to generate one number and then initiating it to start. The generator outputs a random number from within the provided range.
Full Answer >The only common multiple of the numbers 7 and 11 from 1 to 100 is the number 77, according to the Math Warehouse calculator. A multiple is the product of a number and another whole number. A common multiple of 7 and 11 must be larger than the two numbers.
Full Answer >The prime factorization of 72 is 2^{3x} 3^{2}, or 2 x 2 x 2 x 3 x 3. The prime factorization of a number involves determining the factors of a number that are also prime numbers and multiply together to equal the original number.
