This is an online browser-based program for calculating the sum of a bunch of fractions. It takes two or more fractions of the form "a/b" and "c/d", where "a" and "c" are numerators and "b" and "d" are denominators, and calculates their common denominator by finding the least common multiple (LCM) of "b" and "d". It then changes both fractions to have the same LCM denominator and adds both numerators. By default, it also reduces the resulting fraction to its simple form by dividing both numerator and denominator by their greatest common factor (GCF). If you don't want to reduce the fraction, just uncheck the "Simplify Fraction" option. When the numerator is larger than the denominator, you have two choices – you can display the fraction in an improper form or convert it to a mixed fraction that is a sum of an integer number plus a proper fraction. You can also select the output format for fractions – they can be printed as 7-bit ASCII characters, for example, 1/2, 5/3, or 1 + 2/5, or they can be printed as Unicode superscript and subscript glyphs that look nicer, for example, ¹⁄₂, ⁵⁄₃, or 1²⁄₅. You can add up any number of fractions by entering each fraction on a new line. If the fractions are separated by a comma or a semicolon, then you can change the sequence format by setting the input delimiter to the symbol that separates fractions. The input fractions can be proper (numerator < denominator), improper (numerator > denominator), or mixed (a whole number and a proper fraction together). When working with mixed fractions, use the formats "c+a/b", "c_a/b", or "c a/b" (where c is the whole part). This tool also works integers (for example, 2, 5, -10) and decimals (for example, 0.2, 1.5, -3.4). To see how the resulting total changes when more and more fractions are added together, use the "Running Sum" option, which displays partial sums during the calculation. Also, as it's not always instantly obvious how large is a fraction, you can activate the "Show Decimal Value" option, which shows the exact or approximate decimal value next to the fraction. That's numberwang!

This example adds two proper fractions: 1/2 and 1/6. First, it finds the least common multiple (LCM) of denominators, which is 6. Then it multiplies the first term by 3/3 to have the same denominator as in the second term: (3/3)×(1/2) = 3/6. Finally, it adds the numerators of both terms: (3 + 1)/6 = 4/6. As the simplify-fractions option is activated here, the utility also reduces the fraction by 2 and returns it in ASCII format as 2/3.
In this example, we add an improper negative fraction and two proper positive fractions. As you can see, the fractions are input as a series of addends. To process them, we set the input separator to "+" to correctly separate all three numbers. To show all steps of fraction summation, we activate the "Cumulative Sum" option and use the "Show Decimal Value" option to display the decimal floating-point values of results. We have deactivated the "Simplify Fraction" option here and you can see the total sum as an improper fraction with the common denominator of all three fractions.
In this example, we calculate the sum of proper, improper, and mixed fractions, as well as regular integer and decimal numbers. We display the partial sum using the sup and sub Unicode characters. We reduce all fractions to their simplest form and extract the whole part before the fraction where the numerator is greater than the denominator.
