Ability to generate random invoices according to the rules set by the compiler. With ID, the random number can be used in the text of the content blocks, and in the case of an open answer gap, it can be used in the answer evaluation matrix.
Random numbers are generated when you open a task. If there is a desire to use different random numbers, they must all be entered as separate content blocks. A random number is referred to in the text with the Random Number ID enclosed in logical brackets. For example, if there is an operation in the text where it is necessary to add two random numbers with IDs J1 and J2, it is written as follows: {J1}+{J2}=
The solver sees in the text random numbers generated based on the rules created by the creator of the task and must enter the correct answer in the open answer gap. In the evaluation matrix of the gap with an open answer, you must indicate "Type of value" either an integer or a real number, depending on which random numbers are generated, and put a check mark in front of the "Formula" option. The same operation with random number IDs can then be written in the evaluation matrix, but without logical brackets. In the above example, J1+J2 should be entered in the answer field of the evaluation matrix. In this case, the answer is judged to be correct if the solver enters the sum of the two random numbers shown to him in the answer box.
