What is arithmetic?
October 15, 2011
What is exactly arithmetic?
Priyam - India
Arithmetic is working with numbers, such as counting, adding, subtracting, multiplying and dividing. Dividing breaks numbers into fractions and decimals, which are a sub-set of arithmetic.
Fraction has multiple instead of addition
September 3, 2011
What if a fraction has a multiple in the middle instead of an addition
Lwandisa - South Africa
See Multiplying Fractions to see how to do it.

Algebra problem with trains
October 2, 2010
Two trains of 100 m each in length running in opposite directions cross each other in 6 seconds. If the speed of one train is 48km/hr, find the speed of another train.
Rupesh - India
That is a good Algebra problem, not an Arithmetic problem. I think some data is missing.
Sorry we do not have the solution.
Is zero a negative number or positive number?
June 3, 2010
hello sir, good morning,
my name is irfan i am the student of class 6.
please help me and give me answer.
zero is the negative number or positive? why all the things becomes zero when multiplied with zero?
irfan - USA
For a long time zero was not even considered a number, because it represents nothing. Zero is the turning point between positive and negative numbers, so it is neither positive or negative.
Positive is defined as greater than zero and negative is defined as less than zero.
Multiplying by nothing results in nothing. Thus multiplying by zero results in zero.
Quotients that equal 4 to the negative 5 power
November 19, 2009
On my homework it says that I have to write THREE different quotients that equal 4 to the negative 5 power. I don't know ho to do it except for writing it one way only!:(
Tiffany - USA
4^-5 (4 to the negative 5 power) = 1/4^5 = 1/4*4*4*4*4 = 1/2^10 = 2^-10
I hope that is what your teacher is looking for.
Who named our numerals?
February 27, 2009
Who named our numerals such as One (1), Two (2), Three (3), Four(4) - etc?
One can be spelled ONE or WON.
Two can be spelled TWO or TO or TOO.
Four can be spelled FOUR or FOR or FORE.
How far back into antiquity do these names go?
John Wilbur - Utah of USA
English words come from many sources and other languages. Thus, there are a number of words that sound the same but are spelled differently and have different meanings. They are called homophones or homonyms.
Besides the number examples, there are words like through and threw; rain, rein and reign.
Formula for finding prime numbers
November 5, 2008
Regarding the statement that "there is no formula for finding prime numbers": It is not correct. There are at least two formulas. They are a bit unwieldy, I suppose, and thus not particularly useful for most people, but the formulas exist nonetheless.
I can say this quite certainly because my father wrote one of the formulas many years ago!
George - USA
Thanks for your feedback. You are correct. I updated the sentence to read: "there is no simple formula..."
Don't understand how to reduce using prime numbers
February 2, 2008
I just don't understand how to reduce using prime numbers. What is the best way especially using large numbers and fractions? thank you
Yvette - USA
With a fraction, you are mainly concerned about reducing the denominator into prime factors.
Reducing any number into its prime factors is tedious. Usually, you try dividing the number by the small primes and then work your way up.
For example, supposed you have to find the prime factors of 140. Start trying dividing by 2: 140/2 = 70. Try again by 2: 70/2 = 35. You can see that you can't divide 35 by 2, so try dividing by 3. That doesn't work, so try dividing by the next prime, 5: 35/5 = 7. And 7 is a prime. Thus 140 = 2 X 2 X 5 X 7.
Hopefully, this reader feedback has helped provide information about Arithmetic issues.
Always do your best
