**Q: **Is addition studied more abstractly? ¶

**A: **Yes.

**Q: **Is addition used to model countless physical processes? ¶

**A: **Yes.

**Q: **Is addition taught by the end of the first year of elementary school? ¶

**A: **Yes.

**Q: **Is addition called "tropical multiplication"? ¶

**A: **Yes, and maximization is called "tropical addition", and the tropical "additive identity" is negative infinity.

**Q: **Is addition performed does not matter? ¶

**A: **Yes, Repeated addition of 1 is the same as counting; addition of 0 does not change a number.

**Q: **Is addition commutative: one can change the order of the terms in a sum? ¶

**A: **Yes, and the result is the same.

**Q: **Is addition too large to store? ¶

**A: **Yes, and an arithmetic overflow occurs, resulting in an incorrect answer.

**Q: **Is addition an easy consequence of the laws of integer arithmetic? ¶

**A: **Yes.

**Q: **Is addition the definition of additive inverses? ¶

**A: **Yes.

**Q: **Is addition then extended to progressively larger sets that include the natural numbers: the integers? ¶

**A: **Yes, and the rational numbers, and the real numbers.

**Q: **Is addition associative tells us that the choice of definition is irrelevant? ¶

**A: **Yes.

**Q: **Is addition immediate? ¶

**A: **Yes, defining the real number 0 to be the set of negative rationals, it is easily seen to be the additive identity.

**Q: **Was addition developed by Dedekind as early as 1854? ¶

**A: **Yes, and he would expand upon it in the following decades.

**Q: **Is addition one of the simplest numerical tasks? ¶

**A: **Yes.

**Q: **Is addition used together with other operations? ¶

**A: **Yes, and the order of operations becomes important.

**Q: **Is addition a kind of range-side addition? ¶

**A: **Yes.

**Q: **Is addition also fundamental to the operation of digital computers? ¶

**A: **Yes, where the efficiency of addition, in particular the carry mechanism, is an important limitation to overall performance.

**Q: **Is addition typically the fastest arithmetic instruction? ¶

**A: **Yes, yet it has the largest impact on performance, since it underlies all floating-point operations as well as such basic tasks as address generation during memory access and fetching instructions during branching.

**Q: **Is addition first defined on the natural numbers? ¶

**A: **Yes.

**Q: **Is addition collectively referred to as the terms, the addends or the summands? ¶

**A: **Yes, this terminology carries over to the summation of multiple terms.

**Q: **Is addition forced to be commutative? ¶

**A: **Yes.

**Q: **Is addition defined for two matrices of the same dimensions? ¶

**A: **Yes.

**Q: **Is addition a lower priority than exponentiation? ¶

**A: **Yes, and nth roots, multiplication and division, but is given equal priority to subtraction.

**Q: **Is addition written using the plus sign "+" between the terms? ¶

**A: **Yes, that is, in infix notation.

**Q: **Is addition commutative is known as the "commutative law of addition"? ¶

**A: **Yes, This phrase suggests that there are other commutative laws: for example, there is a commutative law of multiplication.

**Q: **Is addition commutative in general? ¶

**A: **Yes.
