Therefore, the calculation formula generated is "25 × 3+75 × 3".
Step 516: and calculating to obtain a calculation result of the calculation formula.
In the embodiment provided in the present application, the calculation formula generated in step 514 is "25 × 3+75 × 3", and the calculation result is "300".
Step 518: and under the condition that the calculation result is matched with the title rule, generating a title step and an initial title according to the calculation formula, the calculation result and the parameter logic.
In the embodiment provided by the application, the topic generation step and the initial topic "25 × 3+75 × 3 ═ 300" are determined that the calculation result "300" meets "C ═ 1 to 5Zero2 to 2" in the topic rule. Where "25 × 3+75 × 3 ═ 300" is the initial title, and "(25 +75) × 3" is the title step.
In another embodiment provided by the present application, the topic template is "a + B-C ═ D", the topic rule is "a ═ 0 to 99, B ═ 0 to 99, C ═ 0 to 99, D ═ 0 to 99, the intermediate result range is 0 to 99", the calculation formula is "55 + 65-40", and the calculation result is "80", at this time, although the calculation result "80" matches with "D ═ 0 to 99" in the topic rule, the intermediate result "120" of the intermediate process "55 + 65" does not match with "the intermediate result range is 0 to 99" in the topic rule, and therefore it is determined that the calculation result does not match with the topic rule, and no topic can be generated.
Step 520: and randomly hiding at least one parameter or operation symbol in the title step and the initial title to generate a title.
When generating the title, the step of completely hiding the title and the step of randomly hiding one parameter or operation symbol in the initial title can be realized, and the step of writing the title is required. If "25 × 3+75 × 3 _", the title writing step is required to be "(25 +75) × 3 _ ═ 300", and if the title writing step is not performed, the title writing step is prompted to be required.
When generating a title, at least one parameter or operation symbol in the title step and the initial title may also be randomly hidden to generate a title, such as "25 × 3+75 × 3 ═ (++) × 3 ═ 300", or "25 × +75 × (25+75) × 3 ═ and so on.
