# Virtual instructions Quoting [the Jolt docs](https://jolt.a16zcrypto.com/how/architecture/emulation.html#virtual-instructions-and-sequences): > Some instructions, like division, don't neatly adhere to the lookup table structure required by [prefix-suffix Shout](https://jolt.a16zcrypto.com/how/architecture/instruction_execution.html). To handle these cases, the problematic instruction is expanded into a virtual sequence, a series of instructions (some potentially virtual). Most opcodes in ONNX are non-linear, which makes it difficult to provide the structure required by Shout. Thus, we convert an instruction into multiple virtual instructions that behave as one. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://devs.novanet.xyz/jolt-atlas-zkml/onnx/tensor-instructions/virtual-instructions.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
