FX Equation has long had a box command that can be used to place boxes around parts of an equation. 3×3+box(2×2)+3x-4 is rendered as We have now added a number of similar commands You can control the color of the … Continue reading →

We have added three new commands to the inline calculator that support data parameters. For example, if you have defined the following Char parameters $p=char(A,H) and $q=char(F,M) You can down perform the following calculations on the results. {union($p,$q)} will return … Continue reading →

The new Multi parameter allows you to create multiple choice questions that randomise the order of the answers. This means that your multiple choice question can have answers and distractors that vary due to the parameters used AND the correct … Continue reading →

Char parameters allow you to quickly define a list of characters that can then be accessed randomly when regenerating Char parameters are defined using the char command. $p=char(start character, end character) Examples: $p=char(A,Z)                   … Continue reading →

Often, the hardest part of creating a MultiDocs question is setting up a parameter that produces suitable numbers. We have recently released two new options that can help you. New Option For Range and RangeEx The Range and RangeEx parameters … Continue reading →

Data parameters can now be created with bivariate data. $b=data((11,12)(15,19)(21,28)(13.2,19.4),(8,16)) Bivariate data is entered as separate data points, wrapped in parentheses, which are then (optionally) separated with your normal separator. New RandBivariate Parameter Often, the best way to create random … Continue reading →

Data parameters can now support grouped data. $g=data(10~20:2,20~30:6,30~40:4,40~50:2) This data parameter is equivalent to this frequency table. Data Frequency 10 < x <= 20 2 20 < x <= 30 6 30 < x <= 40 4 40 < x … Continue reading →

Data parameters can now support frequency tables. $p=data(10:1, 11:3, 12:5, 13:4, 14:3, 15:2) This data parameter is equivalent to this frequency table. Data Frequency 10 1 11 3 12 5 13 4 14 3 15 2 Each entry in the … Continue reading →

The inclusion of data parameters and random number generating parameters has prompted more statistical functions which can calculate summary statistics. For example. If $p=randnormal(50,15,30), $p will return a data parameter with 30 random numbers which have been taken from a … Continue reading →

We have implemented a new parameter and a number of new calculator commands that allow you to work with words. These allow you to implement probability questions like: If you randomly select a letter from the word MISSISSIPPI, what is … Continue reading →
