An algebraic equation is an equation involving polynomials, for which algebraic expressions may be solutions. If you restrict your set of constants to be numbers, any algebraic expression can be called an arithmetic expression. However, algebraic expressions can be used on more abstract objects such as in Abstract algebra.

Japanese has an interrogative particle, か (ka), which functions grammatically like a question mark. Therefore, the question mark is not historically used Japanese, and still not officially sanctioned for use in government publications or school textbooks, but its popularity has been gradually increasing among younger people.
Expressions are often contrasted with statements—syntactic entities that have no value (an instruction). Representation of the expression (8 − 6) × (3 + 1) as a Lisp tree, from a 1985 Master's Thesis [44] Except for numbers and variables, every mathematical expression may be viewed as the symbol of an operator followed by a sequence of ...
For a number written in scientific notation, this logarithmic rounding scale requires rounding up to the next power of ten when the multiplier is greater than the square root of ten (about 3.162). For example, the nearest order of magnitude for 1.7 × 10 8 is 8, whereas the nearest order of magnitude for 3.7 × 10 8 is 9.
We recover the previous relation (a − b = k m) by subtracting these two expressions and setting k = p − q. Because the congruence modulo m is defined by the divisibility by m and because −1 is a unit in the ring of integers, a number is divisible by −m exactly if it is divisible by m. This means that every non-zero integer m may be ...
In mathematics, an infinite expression is an expression in which some operators take an infinite number of arguments, or in which the nesting of the operators continues to an infinite depth. [1] A generic concept for infinite expression can lead to ill-defined or self-inconsistent constructions (much like a set of all sets ), but there are ...
The KB test is the standard method of quantitating fetal–maternal hemorrhage (FMH). It takes advantage of the differential resistance of fetal hemoglobin to acid. A standard blood smear is prepared from the mother's blood and exposed to an acid bath. This removes adult hemoglobin, but not fetal hemoglobin, from the red blood cells.
