![]() ![]() However, the adverb ”strictly” may still be necessary in some of the other contexts described avove. Hence, the terms ”strictly positive” and ”positive” are synonyms here. Browse the definitions using the letters below, or use Search above. Median The middle number of an ordered number of items. Average (Arithmetic Mean) The result of adding all numbers and then dividing by the number of items. (Here, in Planet Math, we have taken the third option by adopting the convention that zero is neither positive nor negative. Easy-to-understand definitions, with illustrations and links to further reading. Percent Another way of writing a fraction. Therefore, it is prudent to write either “x is strictly negative” or “x is non-positive” unless the distinction is unimportant or the context makes obvious which meaning is intended or it has been explicitly stated that the term ”positive” is to be used in only one sense. Synonyms for EQUAL: equitable, impartial, objective, square, indifferent, unbiased, fair, just Antonyms of EQUAL: partial, unjust, partisan, inequitable, biased. The symbol for equal is, which we use to separate the two sides of equations. For example, if you and your friend both bring 2 packets of chips on a trip, you brought an equal number of things. Similarly, the ceiling function maps x to the least integer greater than or equal to x, denoted x or. In mathematics, the term equal means that two or more values or expressions are the same. Seeing a formula like e limn(1 + 1 n)n e lim n ( 1 + 1 n) n for the first time a naive reader would look for an e e on the foregoing. In mathematics and computer science, the floor function is the function that takes as input a real number x, and gives as output the greatest integer less than or equal to x, denoted x or floor (x). Two mathematical expressions are said to be equal if they show the same outcome after they are resolved. Each type of numbers, such as fractions, decimals, or square roots, can be equal to other numbers of their type, or numbers of various kinds, as long as they have the same value. Its only natural to express such an equality by a nonsymmetric symbol such as . Equivalent numbers are numbers of the same value. For instance, upon reading the phrase “x is negative”, it is not immediately clear whether x = 0 is possible, since some authors consider zero to be positive while others consider zero not to be positive. An 'equality by definition' is a directed mental operation, so it is nonsymmetric to begin with. ![]() Each group has ice creams, and there are two such. ![]() To understand better, let us take a multiplication example of the ice creams. Consider the quadratic ax2+bxc, the discriminant of this equation would equal b2-4ac, and it would certainly look like this: b2-4ac. In math, multiply means the repeated addition of groups of equal sizes. Using such terminology helps avoid possible ambiguity and confusion. Multiplication is one of the four basic arithmetic operations, alongside addition, subtraction, and division. ![]()
