what is a factor in a multiplication problem
Multiplication The numbers to be multiplied are generally called the "factors". The number to be multiplied is called the "multiplicand", while the number of times the multiplicand is to be multiplied comes from the "multiplier". Usually the multiplier is placed first and the multiplicand is placed second,[1] however sometimes the first factor is the multiplicand and the second the multiplier.[6] Additionally, there are some sources in which the term "multiplicand" is regarded as a synonym for "factor".[7] In algebra, a number that is the multiplier of a variable or expression (e.g., the 3 in 3xy2) is called a coefficient.
Order of operations These mnemonics may be misleading when written this way,[6] especially if the user is not aware that multiplication and division are of equal precedence, as are addition and subtraction. Using any of the above rules in the order "addition first, subtraction afterward" would incorrectly evaluate the expression[6]
Limit of a function (the Dirichlet function) has no limit at any x-coordinate.
1 + 2 + 3 + 4 + ⋯ which increases without bound as n goes to infinity. Because the sequence of partial sums fails to converge to a finite limit, the series does not have a sum.
