In this category you'll find calculators related to **mathematics** (math). Here you'll find tool allowing you to perform columnar addition on computer screen, see how to add two fractions or learn how to use **law of sines** to find missing angles in the triangle.

Calculator to add numbers. It displays the sum of any given numbers. It also displays columnar addition of these numbers, the carrying (regrouping), partial sums etc. Can be useful for primary school students (learning how to do columnar addition), for financial operations (can be set up to display dollar/cent format) and... for any other addition related purpose.

Fraction explorer - it displays info related to given fraction. Simply enter a fraction and get equal proper fraction, improper (top-heavy) fraction and simplified fraction. Displays also numerator and denominator factors.

Calculations on fractions - it performs operations on two given fractions. Simply enter two fractions and get them added, subtracted, multiplied and divided by each other. You will get sum, difference, product and quotient of these two.

Calculator shows how to add or subtract two fractions step by step. Simply enter two fractions, select add or subtract and get list of all partial steps needed to compute result. Train your math with calculla!

Calculator compares two fractions and tells you if they are equal or different. If given fractions are different, the calculator will let you know which one is greater, which one is smaller and what is the difference between them.

Calculator finds multiplicative inverse of given fraction or number.

Greatest Common Divisor (GCD) calculator - solves GCD for given numbers, but also displays prime dividers (in a school-like way). So, you know how the solution is found. It can find the GCD for 3 numbers too !

Least Common Multiple (LCM) calculator - finds LCM for up to three given numbers and shows process of dividing by primes as for school-like interpretation.

Multiplication table with changable size

Table contains names of large numbers such as million, milliard, billion etc., but also less common e.g. quintilliard. Calculator supports two naming systems (so-called scales): "short scale" (used in most English-speaking countries e.g. UK or USA) and "long scale" (used in most of continental Europe countries).

Calculator computes average and median values from the list of numbers. Find average and median.

Calculator finds maximum and minimum from the list of numbers. Find min/max values.

Calculator accepts list of numbers and displays common statistics about them: average (mean), median, minimum, maximum etc. Summary information about your data series.

Numeral system converter - converts numbers from one number base to another. Calculator supports popular number bases such as decimal (10), hexadecimal (16), binary (2), but also more exotic like ternmary (3), hexavigesimal (26) or duosexagesimal (62).

Calculator finds solutions to common percentage problems. It's done in easy way: more like stories and everyday situations, less like math language.

Prime numbers and factors online calculator (really fast). Give it an integer number, and you got the answers: Is the number prime? If not, what are prime factors? What are results of dividing by prime factors ? What is next/previous prime number ? All of those questions answered here. Used computation method makes this prime number calculator one of the fastest in the web.
