5) (casual, joking) «Does not compute» in a robot voice means this makes no sense. [tree →](https://md.mova.elamur.ai/free/en/corpora/dictionaries/school/C/compute/#m5)

### sense in the lessons

A formal word for «calculate», used in maths questions: «compute the sum», «compute the area». It is the root of «computer». «It does not compute» is a joke way to say something makes no sense. In the exam voice: «Compute the total expenditure incurred», «Compute the mean». In casual talk: «do the maths», «add it up», «crunch the numbers». Phrases: compute the total, compute the average, compute the area.

### note

Regular verb: computed. Nouns: computation, computer. In a maths problem «compute» means calculate; it does not tell you which operation to use. Same family of exam words: calculate, determine, evaluate, ascertain. «Expenditure incurred» (formal) = money spent. «Doesn't compute» means it makes no sense, not a sum.
