Calculating the factors of 25 is straightforward as they are 1, 5 and 25. The first two factors to be ascertained, sometimes the only two factors, are the number itself and 1. Also, any number that can be divided by itself becomes a factor.
Know MoreA factor is a number that can evenly be divided into another number. Any number can be divided by itself and one, so those two numbers are always factors. Numbers that can only be divided by 1 and themselves are called prime numbers. When two numbers have no prime factors in common, its greatest common factor is 1. Some numbers have several factors, and some numbers have just the number and 1.
Learn MoreThe arithmetic sum formula is Sn = n/2 {2a + (n-1) d} where Sn is the sum of n-terms of an arithmetic progression, the first term is ‘a’ and the common difference between any two consecutive terms is given by d.
Full Answer >Twenty pounds converts to 9.07 kilograms. The metric system represented an attempt to bring standardization and sense to the imperial system, which had been in use throughout the British Empire and elsewhere. However, problems arose from a lack of standardization.
Full Answer >There are many arithmetic practice problems to choose from that cover all different levels of math skills. For early learners in pre-kindergarten, addition problems such as 1 + 2 , 1 + 3 and 1 + 4 are great for teaching beginning math skills. Young children can benefit from addition or subtraction problems with higher numbers, but it's good to challenge them a little more by adding simple multiplication problems.
Full Answer >The standard form is 9,319,000. The individual numbers written in expanded form are 8,000,000 + 1,200,000 + 110,000 + 9,000, and the solution is obtained by adding all the digits that fall in the same place values.
