valueA nCr valueB

Returns the number of combinations of valueA taken valueB at a time.

value nCr list

Returns a list of the combinations of value taken each element in list at a time.

list nCr value

Returns a list of the combinations of each element in list taken value at a time.

listA nCr listB

Returns a list of the combinations of each element in listA taken each element in listB at a time.

n/d

Displays results as a simple fraction.

nDeriv(expression,variable,value[,H])

When command is used in Classic mode, returns approximate numerical derivative of expression with respect to variable at value, with specific tolerance H.

In MathPrint mode, numeric derivative template pastes and uses default tolerance H.

4 n/d 3 4 Un/d

Converts the results from a fraction to mixed number or from a mixed number to a fraction, if applicable.

4Nom(effective rate,
compounding periods)

Computes the nominal interest rate.

Normal

Sets normal display mode.

normalcdf(lowerbound,upperbound[,m,s])

Computes the normal distribution probability between lowerbound and upperbound for the specified m and s.

normalpdf(x[,m,s])

Computes the probability density function for the normal distribution at a specified x value for the specified m and s.

NormProbPlot Plot#(type,Xlist,[,freqlist,color#])

Used as the "type" argument in the command

Where # gives Plot1, Plot2 or Plot3.

not(value)

Returns 0 if value is ƒ 0. value can be a real number, expression, or list.

valueA nPr valueB

Returns the number of permutations of valueA taken valueB at a time.

value nPr list

Returns a list of the permutations of value taken each element in list at a time.

list nPr value

Returns a list of the permutations of each element in list taken value at a time.

listA nPr listB

Returns a list of the permutations of each element in listA taken each element in listB at a time.

npv(interest rate,CF0,CFList[,CFFreq])
