Pluses and Minuses: How Math Solves Our Problems

Product Information

As with so many other scare stories, there is a grey area in the middle - and more agreement among the experts than the headlines would suggest. To sort the fact from the fiction we need to rewind a few years. Managing or eliminating risk factors, where possible, may help reduce muscle pain. People can also speak with a doctor about lowering their dosage, trying a different statin, or trying an alternative medication. In many contexts, it does not matter whether the second or the third of these usages is intended: −5 is the same number. When it is important to distinguish them, a raised minus sign ¯ is sometimes used for negative constants, as in elementary education, the programming language APL, and some early graphing calculators. [a] Some elementary teachers use raised minus signs before numbers to disambiguate them from the operation of subtraction. [ citation needed] The same convention is also used in some computer languages. For example, subtracting −5 from 3 might be read as "positive three take away negative 5", and be shown as

The hyphen-minus sign, -, is the original ASCII version of the minus sign, which doubles as a hyphen. It is usually shorter in length than the plus sign and often at a different height to the plus-sign's cross bar. It can be used as a substitute for the true minus sign when the character set is limited to ASCII. Most programming languages and other computer readable languages do this, since ASCII is generally available as a subset of most character encodings, while U+2212 is a Unicode feature only. Also several other software programs usable for calculations do not accept the U+2212 minus. For example, pasting =3−2 into Excel or 3−2= into the Windows calculator won't work. Some annuities charge fees, Brabham says, while others don’t. But for those that do, the fees might be 2% to 3% per year. That fee range is higher than the range for some other investment types. Investors and financial advisors might find annuity fees “troubling, ” Brabham says. Statins also help protect the cardiovascular system in other ways. According to the same research article, statins can: There are a few different kinds of statin. Although they all have a similar function, doctors may recommend trying a few different options to see which works best for someone.Schwartzman, Steven (1994). The words of mathematics.

The problem Strange Bank Account uses the context of depositing and withdrawing money, but does not have such a strong analogy to explain all four possibilities captured in the tables above. However, it can be used to introduce the concept of directed number, and then used in conjunction with another model.

Although it is rather common to verbalise ± 1 as “ positive or negative 1”, this is not technically correct, and “ plus (or) minus 1” is the logical and arguably correct verbalisation.According to a study in the Journal of the American College of Cardiology, people taking statins sometimes have abnormal liver function test results — particularly when they first begin taking them. It is unclear if statins cause this. In the International Phonetic Alphabet, subscripted plus and minus signs are used as diacritics to indicate advanced or retracted articulations of speech sounds. Most annuities let an owner take out a designated portion of their money, frequently 10% each year, without paying a surrender charge during the surrender period (usually six to eight years). If the withdrawal happens before age 59½, you’ll be slapped with a tax on “ordinary” income and potentially a 10% federal income tax penalty. Earliest Uses of Symbols of Operation".

Thanks to Alan Mesfin who suggested an alternative of tying on helium balloons (as in the film "Up") instead of adding puffs of hot air to represent adding a positive number.

Since your first query's 1 ± 1 means 1 + (±1), all these ±1s are the exact same object, and are all read aloud as “plus (or) minus 1”. The liver makes bile acids, which are needed for digestion, using cholesterol. Sequestrants bind to bile acids, making the liver use the extra cholesterol to produce more bile acids. This lowers the cholesterol in the blood. Combination cholesterol absorption inhibitor and statinIn C and some other computer programming languages, two plus signs indicate the increment operator and two minus signs a decrement; the position of the operator before or after the variable indicates whether the new or old value is read from it. For example, if x equals 6, then y = x++ increments x to 7 but sets y to 6, whereas y = ++x would set both x and y to 7. By extension, ++ is sometimes used in computing terminology to signify an improvement, as in the name of the language C++. In his 1489 treatise, Johannes Widmann referred to the symbols − and + as minus and mer (Modern German mehr; "more"): "[...] was − ist das ist minus [...] und das + das ist mer das zu addirst" [9] [10] [11] They weren't used for addition and subtraction in the treatise, but were used to indicate surplus and deficit; usage in the modern sense is attested in a 1518 book by Henricus Grammateus. [12] [13] One of the most touted features of the new Xbox and PlayStation is how their CPU, GPU, and storage subsystems are interconnected. DirectStorage is the equivalent for PCs. In some places, you may find that others say simply "plus minus". In other places, those who work with you may find it strange to hear this pronunciation. There is no universal rule. Generally, you should say "plus or minus", unless you discover that others in some place say "plus minus". Then, you might say either, as long as you remain in the same place. American English In regular expressions, + is often used to indicate "1 or more" in a pattern to be matched. For example, x+ means "one or more of the letter x". This is the Kleene plus notation.
