This is part of arithmetic, a branch of mathematics. Performing addition is one of the simplest numerical tasks. In primary education, students are taught to add numbers in the decimal system, starting with single digits and progressively tackling more difficult problems. The result is expressed with an equals sign. A whole number followed immediately by a fraction indicates the sum of the two, called a mixed number. This notation can cause confusion since in most other contexts juxtaposition denotes multiplication instead.

The sum of a series of related numbers can be expressed through capital sigma notation, which compactly denotes iteration. All of the above terminology derives from Latin. Using the gerundive suffix -nd results in „addend“, „thing to be added“. Likewise from augere „to increase“, one gets „augend“, „thing to be increased“. Redrawn illustration from The Art of Nombryng, one of the first English arithmetic texts, in the 15th century. Sum“ and „summand“ derive from the Latin noun summa „the highest, the top“ and associated verb summare. It appears in mathematical works dating back to at least 1489.
