Marian Said:How can I perform the multiplication and division without using arithmetic operator in c++?We Answered:bit shifting and addition and subtraction.
say I want to multiply my integer NUM by 5.
Each time you bitshift to the left by 1 space you multiply by 2. So we bitshift left twice (NUM<<2) to get 4x and add it to itself once.
NUM = (NUM<<2)+NUM; //this is a multiplication by 5 without using the multiplication sign.
If you need to divide you bit shift to the right >>
If you mean without using the actual signs to do the same work you can overload operators like...
Alvin Said:How does visual basic treat mixed modes of arithmetic operations?We Answered:To solve your problem change the numbers to Int64 or Long.
CType(Number, Long) then you can calculated anything you wish.Christopher Said:How does one prove that the arithmetic operations extend into the complex numbers?We Answered:Early in the last century Bertrand Russell and Alfred North Whitehead set out to "prove" the basis of mathematics using formal logic. After about 350-some pages, they'd proven that 1 + 1 = 2. Maybe you should have a lot of paper handy before you attempt your "proof."

"The math skills assessed by the ASTB subtests include arithmetic and algebra, with some geometry. The assessments include both equations and word problems. Some items require solving for variables, others are time and distance problems, and some require the estimation of simple probabilities. Skills assessed include...
Valerie Said:ALGEBRA 2. Modular Arithmetic Questions!?We Answered:Perhaps your teacher needs to figure out the "mods" and get back to you. Solve for x is easy (it's a review of Algebra 1).
3x-6 + = 2
3x = 8
x = 8/3Carla Said:arithmetic worksheet?We Answered:uhh ok we're just answering this one for the 2 points!Johnny Said:practice with arithmetic ?We Answered:webmath.comBeth Said:Help with this Book: The Devil's Arithmetic?We Answered:Because he has to recite the four questions during the Seder, and he is afraid he will not remember them.Claire Said:Help on 4 problems, please...arithmetic means, summation notation?We Answered:1. say, common difference is d.

Lewis Said:Binary Arithmetic?We Answered:A. (Making assumption here that only dealing with positive numbers and that 'represented by x bits' means x is the maximum storable.)
10100 + 11001 = 101101 without consideration of storage.
A1. Since only 5 bits storable, the high order bit is lost, resulting in 01101 or 13 in decimal.
A2. No high-order overflow, so result is the entire number or 45 in decimal.
B. Not entirely sure on this one, as been quite a while since I dealt with 2's complement. However, pretty sure in 2's comp a high-order bit indicates a negative value, so looks like another overflow situation...
Duane Said:Label the following sequences as geometric or arithmetic?We Answered:2, -4, 8, -16 is geometric, r= -2
1, 2, 3, 5, 8 is neither.Eileen Said:What is arithmetic, geometric and harmonic means of the three roots of qubic polynomial x³ - ex² - x + π?We Answered:if the roots are a, b, c then
P(x) = x³ - (a+b+c)x² + (ab+ac+bc)x - abc
So a+b+c = e
abc = -π
ab+ac+bc = -1
1/a + 1/b + 1/c = (ab+ac+bc)/abc = 1/π
arithmetic mean = (a+b+c)/3 = e/3
geometric mean = ³√abc = -³√π
harmonic mean = 3 / (1/a + 1/b + 1/c) = 3πRicky Said:Arithmetic and geometric sequence...
Karen Said:What does IAS stand for?We Answered:From a computer viewpoint, it could mean Internet Authentication Service (IAS). Microsoft Development has a webpage on this service. It is technical in nature but it could help explain the process.

Adrian Said:Answers for If the physiological density is much higher than the arithmetic density, then a country has?We Answered:sorry - looks like you should be in geography not physicsKatherine Said:Can you help me with this arithmetic sequence and series word problem?We Answered:Well, we know that they were penalized $5,000 a day for the first 5 days. $5,000 x 5 = $25,000
For each day after, they get penalized $200 more a day than the day before.
If you subtract 25,000 from 65,600, you're left with 40,600.

And never mind 1895, in a TV programme, they took twenty bright teenagers all predicted to get top grades in their exams and made them attend a Fifties-style school where at the end they would sit 1955 exams. A few of the kids scrapped a low pass while the rest failed miserably.Kelly Said:I, in all honesty, have no real aptitude for anything.
