How it's used

Primarily used to express frustration or helplessness when facing complex, messy, or impossible calculations. It carries a sense of being overwhelmed by the sheer scale or lack of clarity in the data. While it sounds like a formal ban, it is strictly a colloquial way to describe a mental or practical block in arithmetic.

Examples

This thing is really hard to calculate, no matter how I count it, the numbers don't match.
The number is so huge, how do you expect me to calculate it?

Common phrases

completely impossible to calculate
really hard to calculate

Common mistake

Do not confuse this with the formal term 禁止 which means to prohibit. Learners often mistake the sound for a legal restriction, but in this context, it functions purely as an adjective or verb describing the difficulty of computation.
