An irreducible fraction (or fraction in lowest terms, simplest form or reduced fraction) is a fraction in which the numerator and denominator are integers that have no other common divisors than 1 (and −1, when negative numbers are considered). [1]
In mathematics, a negative number is the opposite of a positive real number. [1] Equivalently, a negative number is a real number that is less than zero. Negative numbers are often used to represent the magnitude of a loss or deficiency. A debt that is owed may be thought of as a negative asset.
For single digit numbers simply duplicate the number into the tens digit, for example: 1 × 11 = 11, 2 × 11 = 22, up to 9 × 11 = 99. The product for any larger non-zero integer can be found by a series of additions to each of its digits from right to left, two at a time. First take the ones digit and copy that to the temporary result.
They focused on shopping motivations and found that the variety of products available and the perceived convenience of the buying online experience were significant motivating factors. This was different for offline shoppers, who were more motivated by time saving and recreational motives. Michael Aldrich, pioneer of online shopping in the 1980s

And the numbers speak for themselves: Nvidia: if you invested $1,000 when we doubled down in 2009, you’d have $302,501 !* Apple: if you invested $1,000 when we doubled down in 2008, you’d have ...
I have been investigating negative numbers in quadratic equations for a school project and I just can't sort out the history. Some people don't allow negative coefficients, and that means you can't have a single method of solution. Others don't use negative numbers in the calculations, which is almost the same thing.
The depleted harmonic series where all of the terms in which the digit 9 appears anywhere in the denominator are removed can be shown to converge to the value 22.92067 66192 64150 34816.... [44] In fact, when all the terms containing any particular string of digits (in any base) are removed, the series converges. [45]
